Remember him? Of course you do.
He was President Bush's Secretary of Defense. He's the guy who got every single thing wrong about the Iraq War, beginning with starting it, how long it would take, how it would "pay for itself," how we'd be greeted as liberators, and every other aspect of it. During his and Dubya's watch, the US suffered the biggest security failure in American history, with the worst terrorist attacks and 3,000 people killed on 9/11.
Remember how he claimed he knew exactly where the non-existent weapons of mass destruction were?
"We know where they are. They're in Tikrit and Baghdad, and east, west, south and north."
That narrows it right down.
Remember how he replied to the complaints about sending US troops to war without adequate body armor?
"You go to war with the army you have, not the army you might want or wish to have."
And the circular classic:
"There are known knowns; there are things we know we know. We also know there are known unknowns; that is to say we know there are some things we do not know. But there are also unknown unknowns; the things we don't know we don't know."
When this total failure was asked at a recent rightwing interview, by a member of the audience, whether President Obama has actually switched sides in the war on terror, he replied, "I don't feel competent to answer. I don't know."
You're not sure if the President of the United States is on the terrorists' side, you Jackass?
Say something like that during the Bush years and you'd be called anti-American, unpatriotic, and treasonous.
Need I point out that President Obama was the one who actually got Osama Bin Laden, at which Rummy and Dubya failed for eight years? Should I mention that al Qaeda's leadership has been devastated under the current President? And despite all the obsession about Beghazi, it was the only attack of its kind during President Obama's first five years -- compared to 13 similar attacks under Bush?
Nah. No need. We'll just label Donald Rumsfeld the Jackass that he is, and move on.
