national security & defense
National security policy in the U.S. balances protecting the nation from external and internal threats with civil liberties, evolving from Cold War frameworks to post-9/11 counterterrorism priorities.
general notes
national security includes diplomacy, economic leverage, armed forces, emergency preparedness, and intelligence
civil defense and critical infrastructure resilience are core pillars
post-9/11, concerns grew about the trade-off between security and civil liberties
measures taken to ensure US national security
using diplomacy to rally allies and isolate threats
using economic power to elicit cooperation
maintaining effective armed forces
implementing civil defense and emergency preparedness policies (e.g. anti-terrorism legislation)
ensuring the resilience of critical infrastructure
using intelligence services to detect, defeat, or avoid threats and protect classified info
tasking counterintelligence services or secret police to address internal threats
structure of national security
national security organizations have remained mostly stable since President Harry Truman signed the National Security Act of 1947 and its 1949 amendment
the act led to:
the creation of the national military establishment, now the Department of Defense
a separate department of the Air Force from the existing Army Air Forces
subordinating all military branches under a new Secretary of Defense
the establishment of the National Security Council to coordinate security policy in the executive branch
the Central Intelligence Agency (CIA), a civilian agency tasked with advancing U.S. national security through foreign intelligence gathering and undercover missions
post WW2 foundations
Democratic president who served from 1945 to 1953

the september 11 attacks
four coordinated Islamist terrorist suicide attacks carried out by 19 Al-Qaeda operatives
two planes crashed into the Twin Towers (World Trade Center) in NYC
one crashed into the Pentagon in Virginia
the fourth crashed into a field in Pennsylvania during a passenger revolt
killed 2,977 people, the deadliest terrorist attack in history
led to the war on terror, a global military campaign led by the U.S. that some argue replaced the Cold War
headquarters of the Department of Defense
decades-long political and military rivalry between U.S. and Soviet Union after WWII, nuclear tension but no direct war
response to 9/11: war on terror
counterterrorism center identified the attacks as carried out by Al-Qaeda, led by Osama bin Laden
U.S. launched the War on Terror, beginning with the invasion of Afghanistan
goal: depose the taliban, who had refused to expel al-qaeda or extradite its leaders
motives cited for 9/11 attacks included:
U.S. support of Israel
U.S.-led attacks in Somalia and the Moro conflict in the Philippines
sanctions on Iraq
environmental destruction
ongoing insurgency in southern Philippines, Muslim groups' fight for independence from central government since the 1970s
a militant Islamist terrorist group founded by Osama bin Laden in 1988
war in Afghanistan (2001)
started with broad support
shifted from targeting Al-Qaeda to long-term nation building
became the longest war in U.S. history, with limited clear progress
involved use of Guantanamo Bay, a military prison in Cuba to detain terror suspects
CIA operated black sites where torture (e.g. waterboarding) occurred
these actions damaged the U.S.’s global reputation
iraq war (2003)
President George W. Bush labeled Iraq part of the “axis of evil”
claimed Saddam Hussein had weapons of mass destruction (WMDs) and ties to terrorism
U.S. invaded in march 2003, no WMDs were found
war dragged on for years, costing thousands of U.S. and Iraqi lives
destabilized the region and was later seen as unjustified and based on false intelligence
widely viewed as a mistake in hindsight
