Saddam Hussein's Iraq possesses weapons of mass destruction - a certainty cited repeatedly by US and UK government officials.

Now we know:

No weapons of mass destruction were found in Iraq after the 2003 invasion. The intelligence was flawed, misrepresented, and in some cases fabricated. The Iraq Survey Group concluded Saddam had ended his WMD programs in 1991.

What changed?

In the years following the September 11, 2001 attacks, American high school students learned that Iraq possessed weapons of mass destruction. The claim appeared in news broadcasts, presidential addresses, and classroom discussions of current events. It was not presented as a possibility or an intelligence assessment, it was taught as a confirmed fact requiring a military response.

The certainty had historical grounding. Iraq had used chemical weapons extensively during the Iran-Iraq War in the 1980s, killing thousands of Iranian troops and Kurdish civilians in attacks that included the 1988 Halabja massacre. Saddam Hussein's regime had pursued biological, chemical, and nuclear weapons programs until the 1991 Gulf War, when UN inspectors located and destroyed stockpiles and production facilities. The question framed to the public in 2002 and 2003 was not whether Iraq had resumed these programs but what form the threat now took.

Secretary of State Colin Powell addressed the United Nations Security Council on February 5, 2003, delivering what the administration positioned as definitive proof. For seventy-five minutes, he presented satellite images, intercepted communications, and intelligence assessments. "My colleagues, every statement I make today is backed up by sources, solid sources," Powell said. "These are not assertions. What we're giving you are facts and conclusions based on solid intelligence." He described mobile biological weapons laboratories, aluminum tubes for uranium enrichment, and ongoing efforts to acquire nuclear materials. President Bush's State of the Union address had already cited British intelligence claiming Iraq sought uranium from Africa. The National Intelligence Estimate of October 2002 concluded that Iraq was reconstituting its nuclear program. The rhetorical certainty matched the stakes: imminent danger requiring immediate action.

The invasion began March 20, 2003. Saddam Hussein's government collapsed in April. Coalition forces began the search. Inspection teams fanned out across suspected weapons sites, following intelligence leads accumulated over years of surveillance. They found nothing.

The Iraq Survey Group, a 1,400-person task force assembled specifically to locate Iraq's weapons programs, spent eighteen months searching. Its final report, released in September 2004, concluded that Iraq had ended its nuclear, chemical, and biological weapons programs in 1991 following the Gulf War. The regime had not restarted them. There were no stockpiles. There was no active program. Hussein had maintained deliberate ambiguity about whether he possessed weapons, partly to deter Iran and partly to preserve domestic political standing, a bluff that invited the invasion that destroyed his government and led to his execution in 2006.

The intelligence had been wrong. Powell later called his UN presentation "a blot" on his record, acknowledging he had relied on faulty information. The Senate Intelligence Committee's 2004 report found that the intelligence community's pre-war judgments were "overstated" and "not supported by the underlying intelligence." Some claims had been based on single sources with credibility problems. Others had been inferred from ambiguous evidence given the most threatening interpretation. The certainty presented to the public, to Congress, and to students in civics classes had been constructed from guesswork, worst-case assumptions, and in some instances fabrication.

The correction reshaped how a generation understood government claims about national security. The war killed tens of thousands of Iraqis and more than 4,000 American service members. It cost over a trillion dollars and destabilized the Middle East in ways that contributed to the rise of ISIS. The misrepresentation of intelligence before the war became a case study in institutional failure, in the consequences of allowing policy objectives to shape intelligence assessments rather than the reverse. Students who graduated high school between 2001 and 2004 watched the certainty of the WMD claims give way to admissions of error, a collapse that marked a turning point in public trust regarding official justifications for war.

Mass surveillance programs - collecting metadata and communications at scale - are effective tools for preventing terrorism.

Now we know:

Multiple post-9/11 reviews found that bulk metadata collection programs (NSA's Section 215 program) produced no cases where bulk surveillance was essential to preventing an attack. The Privacy and Civil Liberties Oversight Board concluded in 2014 that the program was illegal and ineffective.

US government statements about the Vietnam War - its progress, objectives, and prospects for success - were accurate and made in good faith.

Now we know:

The Pentagon Papers (published June 1971) revealed that multiple administrations had systematically misled the public and Congress about Vietnam War objectives and prospects. The government had known the war was unwinnable years before admitting it.

Reagan's Strategic Defense Initiative (SDI) is a technically feasible missile defense system that could render nuclear weapons obsolete.

Now we know:

The American Physical Society's 1987 report concluded that SDI was at least a decade from even beginning meaningful tests. The technology Reagan described did not exist and no comprehensive missile defense system exists today.
