So is Syria and Iran.
Seriously, I understand where you are coming from. There are also many American civilians stranded in Lebanon.
Screwy Louie in Iran is coordinating one massive strike against Israel and US interests in Iraq and Afghanistan. The Iraqi and Afghani fronts will be under the guise of insurgent resistance, but the timing will coincide with an offensive against Israel so as to keep our troops off guard and busy. The Iranian Hitler is just crazy enough to do something like this- and probably has a ton of followers ready to do anything at his command.
