Au contraire, you appear to be the one in LA-LA land. You appear to not notice the threats that exist beyond our borders. Those threats are not contained to those beyond our borders but rather to US. Like it or not, the United States has real interests in other parts of the world. Oil is a prime example. Our economy and the world's economy cannot run without it. So, protecting our interests in other parts of the world is necessary for protecting our interests here at home.
You statement that Iraq has been contained for eight years is pointless. So what? That doesn't mean it shall remain so. I favor action versus reaction. As the President stated, he will not wait while others seek to harm us. Look how Sadaam is funding the Palestinian suicide bombers. No doubt he is also funding Al Qaeda.
You have a beef about a declaration of war. Have we gone into Iraq yet? Perhaps the President will ask for a declaration of war when the time is warranted. The President asked and did receive support for a war on terror, for those responsible for the atrocities of 9/11.
We are not policing the world. We are protecting ourselves and our allies. From the way you talk, you seem to think we shouldn't even have allies. Talk about LA-LA land.
