The armed forces of the US are stationed in a forward position...in the heart of the Islamic ME...in relative safety. Iran is pinched between that and an other base to the east. Insurgent radicals are focused on humiliating us there....and we're killing them, if and when possible...capuring them when necessary. You got a better plan? Huh? It was the best possible action. It leads to the broadest set of further, positive options. Good as could have been gotten. And I'm sure it has saved thousands of lives here at home. No one can say for certain. I believe it to be true.
TSA and all that other niggling s**t is what it is. Not that damn important....kinda like the Guantanimo flap and all the other pimpes on the elephant. Just not worth expending mental, physical, and money resources over. Gnats.
Furthermore...we are between Iran and Israel. Adjacent to our allied governments in Turkey, Pakistan, Jordan and Saudi Arabia....all of which are shaking at their foundations from the same Wahhab influence. They draw strength from out presence. We are the world's policeman...on scene...saving the world from pirates who no longer use balls of flaming pitch and long swords to advance their holy imprimatur for plunder. You are near-sighted.
