Steve.. I'd guess that if Isreal moved on Syria she'd be totally isolated.
We'd not support her unless Syrai struck first in a 'pearl harbor' style military attack..
It's just not a smart tool move. I think america will wake up to the fact that Israel is NOT an ally of America in any meaningful way any damn day now.
She propogates terror by grinding palestininas under her heel, is standing in violation of UN resolutions, has refused to cease espionoge activities within our borders, continues to sell US technology to proscribed nations, refuses extradition of american citizens wanted in this country for murder, has used duplictious means to secure funding, has violated the terms for that funding... etc etc etc.
No.. if Syria does not not directly treaten the U.S.; if it does resond correctly to diplomatic demands for known iraq war criminals proven to be under it's protection then Syria need not worry about military interference from America.
While Syria has some dirty rags in it's closet.. the bloody ones in the israli cabinet concern me more.
