AMSCO 9.6 Challenges of the 21st Century

Overview

AMSCO Topic 9.6, "Challenges of the 21st Century," covers the United States from the disputed 2000 election through the Obama years: the September 11 attacks, the wars in Afghanistan and Iraq, the Great Recession, and the deepening partisan gridlock in Washington. The chapter's core argument matches the AP framing for Period 9 (1980-present): the U.S. entered the century with unmatched economic and military power, but terrorism, economic crises, and polarized politics exposed real vulnerabilities even as America remained the world's leading superpower. The big tensions to track are security vs. civil liberties, fossil fuel dependence vs. climate concerns, and government action vs. conservative pushback.

The Disputed Election of 2000

The 2000 election was the closest since 1876 and the first decided by the Supreme Court. Vice President Al Gore (Democrat) faced Texas Governor George W. Bush (Republican), with Green Party candidate Ralph Nader possibly pulling enough votes from Gore in Florida to swing the outcome.

• Gore won the popular vote by about 500,000, but everything hinged on Florida's 25 electoral votes, where Bush led by just 537 votes.
• Democrats demanded manual recounts of error-prone punch card ballots, and the Florida Supreme Court ordered a statewide recount.
• In Bush v. Gore, a 5-4 majority (matching the justices' party loyalties) halted the recount, ruling that Florida's inconsistent recount standards violated the Equal Protection Clause of the 14th Amendment.
• Bush won 271 electoral votes to Gore's 266. Gore accepted the ruling, ending the crisis.

This is a classic APUSH example of contested democratic institutions and the judiciary's expanding political role.

The War on Terrorism

The September 11, 2001 attacks transformed American foreign and domestic policy, leading to long wars in Afghanistan and Iraq and new security measures that raised civil liberties questions.

Roots of terrorism and early attacks

Anti-American sentiment in parts of the Arab world stemmed partly from U.S. support for Israel, but went deeper. After World War I, Western-style secular nation-states replaced the Ottoman Empire in the Middle East. Religious fundamentalists rejected modernization (including equality for women) and called for societies governed by the Quran and Sharia law. Extremists like Osama bin Laden and Al-Qaeda ("The Base") preached jihad against "Jews and Crusaders" to restore an Islamic caliphate.

This was "asymmetric" warfare: a small band of militants inflicting major damage on a far more powerful country.

• 1993: truck bombing of the World Trade Center killed six.
• 1998: bombings of U.S. embassies in Kenya and Tanzania killed over 200, including 12 Americans. The U.S. bombed Al-Qaeda camps in Afghanistan and Sudan in response.
• 2000: suicide bombers nearly sank the USS Cole in Yemen.
• Bin Laden took refuge in Afghanistan, controlled by the Taliban (Islamic fundamentalists).

September 11 and the war in Afghanistan

On September 11, 2001, Al-Qaeda terrorists in hijacked airliners struck the World Trade Center towers and the Pentagon; a fourth plane crashed in Pennsylvania. Nearly 3,000 people died. The attacks galvanized public opinion like nothing since Pearl Harbor.

When the Taliban refused to hand over bin Laden, U.S. bombing, special forces, and the Afghan Northern Alliance overthrew their government in fall 2001. Bin Laden escaped into the mountains near Pakistan, and the U.S.-backed Afghan government stayed unstable, plagued by Taliban insurgency and tribal conflict.

Homeland security vs. civil liberties

The USA PATRIOT Act (2001) gave the government new powers to gather information, expand surveillance, and make arrests. Many Americans worried about wiretaps, mass collection of phone and email data, military tribunals, and indefinite detention of suspects at Guantánamo Bay, Cuba.

The new Department of Homeland Security combined more than 20 federal agencies (Secret Service, Coast Guard, customs, immigration), the largest government reorganization since the Department of Defense was created after World War II. After a 2004 bipartisan commission criticized the FBI, CIA, and Defense Department for failing to "connect the dots" before 9/11, Congress created a director of national intelligence to coordinate all intelligence agencies.

The Iraq War

In his 2002 State of the Union, Bush labeled Iraq, North Korea, and Iran the "axis of evil." The administration claimed Iraq's Saddam Hussein was linked to 9/11 (U.S. intelligence found no such link) and was developing weapons of mass destruction (WMDs). UN inspections found no WMDs.

In March 2003, without UN support, the U.S. launched Operation Iraqi Freedom. In four weeks, U.S., British, and allied forces captured Baghdad and ended Hussein's dictatorship. But no WMDs were found, fueling criticism of a "war of choice" and "regime change." Hussein's capture in late 2003 didn't end the violence: Sunni loyalists, Shiite militias, and foreign fighters (including Al-Qaeda) kept attacking U.S. troops and each other. Photos of prisoner abuse at Abu Ghraib damaged America's reputation worldwide.

The Bush Doctrine

Critics charged Bush with a unilateralist approach: refusing the Kyoto Accord on climate change, dropping the 1972 Anti-Ballistic Missile Treaty, and declining to negotiate with Iran or North Korea. The "Bush Doctrine" argued that containment and deterrence no longer worked against stateless terrorism, so the U.S. was justified in preemptive attacks to stop terrorists or terror-sponsoring states from acquiring WMDs.

Bush's Second Term and Domestic Policy

Bush defeated Democrat John Kerry in 2004 with 51 percent of the popular vote and 286 electoral votes, and Republicans expanded their congressional majorities. His domestic agenda was conservative: tax cuts, deregulation, faith-based initiatives, and school choice.

• Tax cuts. The 2001 cut totaled $1.35 trillion (lower top bracket, eliminated estate taxes, bigger child tax credit, rebates); 2003 cuts targeted dividends, capital gains, and married couples. Democrats said the cuts favored the rich and helped double the national debt from about $5 to $10 trillion.
• No Child Left Behind Act. Bipartisan law using national testing to close achievement gaps between wealthy and poor students. Medicare gained prescription drug coverage.
• Dot-com bust and corruption. The tech boom collapsed by 2002; the Dow fell 38 percent, and Enron and WorldCom "cooked their books." The Fed cut interest rates to 1.25 percent, pushing investors into real estate and inflating a new bubble (2002-2007).
• Hurricane Katrina (2005). FEMA's failed response to the flooding of New Orleans left over 1,000 dead. Katrina, the Iraq War, and GOP scandals helped Democrats take both houses of Congress in 2006.
• Courts. Bush appointed conservatives John Roberts (Chief Justice) and Samuel Alito to the Supreme Court.
• Iraq surge. In 2007 Bush sent 30,000 additional troops; by late 2008 violence and American deaths were down, but Bush handed two unresolved wars to his successor.

The Great Recession and the Election of 2008

The 2002-2007 housing bubble, inflated by fraudulent mortgage lending and securitization (bundling high-risk loans into complex investments sold worldwide), burst into the worst economic crisis since the Great Depression.

• As housing prices fell, foreclosures climbed and trillions in investments lost value, triggering a credit (liquidity) crisis as banks stopped lending.
• The government took over mortgage giants Fannie Mae and Freddie Mac; the September 2008 bankruptcy of Lehman Brothers spread panic.
• Congress passed the Economic Stabilization Act of 2008, creating the $700 billion Troubled Assets Relief Program (TARP). Conservatives called it "socialism"; liberals called it a bailout of the executives who caused the mess.

The crisis shaped the 2008 election. Barack Obama, the 47-year-old senator from Illinois, beat Hillary Clinton for the Democratic nomination and chose Joe Biden as his running mate. He defeated Republican John McCain 364 to 174 in the Electoral College, becoming the first African American president. He inherited two wars and an economy in freefall.

The Obama Presidency: Recovery, Reform, and Gridlock

Obama's two terms (2009-2017) brought major economic and health care legislation, followed by intense partisan deadlock once Republicans gained congressional power.

Stimulus and financial reform

• The American Recovery and Reinvestment Act (2009) provided a $787 billion stimulus: $288 billion in tax cuts, $144 billion for state and local governments, plus construction, health care, renewable energy, and education spending.
• The government took over General Motors through bankruptcy and guided Chrysler's sale to Fiat; "Cash for Clunkers" subsidized fuel-efficient car purchases.
• The Dodd-Frank Act (2010) tightened regulation of banks and investment firms to prevent future "too big to fail" bailouts and created the Consumer Financial Protection Bureau (CFPB).
• By late 2016: 15 million jobs added, unemployment down to 4.6 percent, the Dow up 210 percent. Critics still called the recovery slow.

Health care, environment, education

• The Affordable Care Act (2010), "Obamacare," extended affordable insurance to millions through subsidies, mandates, insurance exchanges, and Medicaid expansion. It required coverage of preexisting conditions and let children stay on parents' plans until 26. About 20 million Americans gained coverage. Republicans tried more than 50 times to overturn or defund it.
• The U.S. joined the Paris Agreement (2015) to cut global carbon emissions; climate became another partisan flashpoint.
• The bipartisan Every Student Succeeds Act (2015) replaced No Child Left Behind, shifting power back to states and localities.

Polarization and deadlock

• The Tea Party, a conservative and libertarian movement opposing government spending and Obamacare, powered the 2010 Republican takeover of the House.
• Citizens United v. FEC (2010) ruled corporations are "legal persons" with the right to buy political ads, flooding elections with new money and weakening the parties.
• Obama won reelection over Mitt Romney in 2012 (332-206, with 71 percent of the Hispanic vote), but Republicans took both houses in 2014.
• Gridlock produced automatic budget cuts (sequestrations), a 16-day government shutdown in October 2013, and a 13-month Supreme Court vacancy after Justice Scalia died in 2016, when Senate Republicans refused hearings for nominee Merrick Garland.

Civil rights advances

Congress made attacks based on sexual orientation or gender identity a federal hate crime (2009) and repealed "Don't Ask, Don't Tell" (2010), ending discrimination against gays and lesbians in the military. Obama publicly supported marriage equality in 2012, and the Supreme Court's Obergefell v. Hodges decision later made same-sex marriage legal nationwide.
