Israeli troops are not fighting along American troops. In fact, Israel has deployed no troops at all under American command.
You people are either daydreaming or spreading misinformation.
Only Britain, Spain, Italy and Australia are sending in war materiel and troops. Those are our true friends.
Anyway, I think we're going in and it will be a short-lived American victory.
You might also want to consider all of the intelligence that Israel has given us over the years - something that lots of other allies couldn't do, simply because they weren't placed appropriately. Each country is unique - they each have strengths and weaknesses in becoming involved in a certain manner, and I'm sure that no one in DC wants Israeli troops fighting an Arab nation alongside ours. It just ain't PC. Besides, Israel may just end up bumping off the Syrian terror regime, which will certainly involve lots of Israeli soldiers and will help the WOT lots more than a few thousand Spanish, Australian or Italian troops, for example. This is not to badmouth those allies, who are doing lots to help us, but to illustrate the contribution that Israel may very well make.
Also consider that the mere possibility of an Israeli assault has tied down the vast majority of Syrian troops, and prevents Syria from contributing to the Iraqi war effort.
