Losing Argument: You can't win a war you don't believe in fighting
"You can't win a war you don't believe in fighting" – George W. Bush, 10/6/04
Why it's a loser:
It conflates two points. First point: knowing what we know now – no WMD, no collaborative relationship with al-Qaeda – it was the wrong decision to go to war. Second point: now that we are there, we have to win. In other words, it is possible to believe that starting something is a bad idea but recognize – once you've begun – you have to finish it. Similarly, if you're pushed off a boat, you may not want to be in the water, but you still have to swim to shore.
