The war with Iran was in the 1980s. The turnover of the weapons was in the 90s after the first gulf war (and not at all before that). The finding of the caches was in 2003-2008.

Bush and Cheney lied. They didn’t find any, and the Bush Administration doesn’t even claim they had them.You won’t admit that you were wrong to support the war.
