Its not that hard to grasp why we can't accept defeat as the dem's want us to.
THE VICE PRESIDENT: Well, it would be very tough. Remember what Al-Qaeda is betting on here. They cannot beat us in a stand-up fight. They never have. What they're betting is that they can break our well, that they can in fact force the American people to retreat, that we'll finally get tired of the battle and go home, and then they win. The only way they can win is if we quit, and to adopt a policy that says, "We're going to withdraw from Iraq," would do precisely that. It in effect hand the victory to the terrorists. It validates the whole Al-Qaeda strategy. The other thing you can be sure of is, once they figure out if they attack America often enough we'll change our policies, they'll keep attacking America.
