Don't be a fool.
Right back at you.
No one cared about Saddam's chemical weapons until it turned out he was never even close to having nuclear ones. The U.S. went into Iraq (for the second time) on the promise that Saddam Hussein had or would soon have a nuclear weapon and that he was likely to use it against the United States or one of it's allies. The information to justify this claim came from a single source, a drug-addicted Iraqi defector who basically said whatever his handlers wanted as long as kept him supplied with booze and drugs. This information was deliberately fed to intelligence agencies of several different countries to create the appearance of multiple sources.
The false pretences were nuclear, when the claims proved too absurdly wrong, the story changed to be chemical weapons, instead. Which Saddam didn't have either since he had long ago used the ones that the United States had provided to him.
