When U.S. Ambassador to the United Nations Nikki Haley on Thursday presented what she claimed was irrefutable evidence that Iran had supplied a missile launched at the Saudi Arabian capital by Houthi rebels in Yemen last month, it was hard not to recall the last time an American diplomat stood before the U.N. with evidence that a rogue Middle Eastern state was engaged in proliferation of dangerous weapons.

As it turned out, then–secretary of State Colin Powell’s 2003 speech explaining the Bush administration’s rationale for going to war with Iraq was based on lies and fabrications, and, of course, Iran says Haley’s evidence is fabricated as well.
