By the way, we don't need to invade anyone.....
Bill Clinton showed we can pretty much bomb countries into submission.(see Milosevic)
===================================================================
No, he pretty much proved that Serbia could be bombed into submission. Serbia was small and puny and had few friends.
Might I suggest that it there is trouble emanating from a country where some people dislike you, if you invade that country or bomb it, it is extremely probable that damn near everyone will utterly loathe you after you do so.
Observe how after about twenty Arabs bombed just three buildings or so in the US, everyone here was willing to attack Afghanistan, amd even Iraq, which harbored not one of the twenty bombers. Had the government chosen to whomp up a little interest, they could have bombed Saudi Arabia, Yemen and several other countries for good measure.
Do we really want everyone in Syria or lebanon to loathe Americans?
I do not think it is in the best interest for the 6% of the world's population that is the USA to want the other 94% to loathe us as mad bombers, invaders, and such.
Plus, we really do not have the manpower to attack all the places mentioned, and this therefore will not happen.
Not even the dumbest fool in the incompetent Juniorbush administration is going to invade Lebanon or bomb it flat, let alone Syria or Iran.
