One of the linchpins on which the Bush administration tried to hang a casus
belli to invade Iraq on were forged Niger documents that claimed Saddam Hussein (no relation to Barack Hussein Obama) was trying to buy yellowcake uranium for his (non-existent) weapons of mass destruction program. Later, Joseph Wilson, sent on a fact-finding tour discovered them to be fakes and said so in a New York Times op-ed piece that eventually led to the outing of his wife as a CIA agent by members of the Bush administration.
In 2005, the US toured the world with a stolen laptop computer they touted as evidence Iran was developing nuclear weapons with it's uranium enrichment program, not nuclear power. This was contrary to the National Intelligence Estimate that stated Iran had given up it's nuclear ambitions two years earlier. Now, as it turns out, the documents may have been fabricated. Gee, ya think? Someone in the Bush madministration faking evidence to start a war in another Middle East country rich with oil?
