I just think we need to be realistic. If you want to think in historical terms, all you have to do is look at what happens when countries try to cross the ocean to invade other countries, far, far away from their own. It just isn't practical in most cases, and it isn't close to being practical in our case.

No one is going to sail across the ocean to invade the US, it would be a logistical nightmare. We could cut our army by 80%, our navy and air force in half, and we would easily crush anyone attempting to invade us. Heck, half the world could try to invade us and we would still crush them into the ground.

Besides, we are not even talking about our defense. We are talking about sending troops half way around the world. It is totally impossible for a country like iran or iraq to invade the US. That isn't even on the table. No one thinks it is possible. We are talking about terrorists attacks. And since when did a 80 million dollar bomber, ever stop a terrorist attack?
