As Americans, we're just not the hide and cringe types.
"Are we safer now than we were before we began to fight back against the terrorists? Perhaps not, just as we were not safer when we began to resist Hitler, prompting him to declare war on us. Back then, we were not safer until we had won."
Bingo. What confuses the appeasers is the claim that we are safer. No one knows for sure right now whether or not we are safer today. It can even be argued that we are less safe. We're like the school kid telling the bully, 'No, you can't have my lunch money.' Does that make you safer? Not really. Not at first. But when the bully is on the ground with a bloody nose, you'll feel ten feet tall. And when the bully comes to school the next day and you see fear in his eyes, and he avoids you, then you know you are not only safer, but free, unlike the rest of the school.
