Are you suggesting that Israel gave troop aid for Operation Enduring Freedom? I find the notion that everybody would have abandoned us for accepting Israel's aid kind of suspect.
Quit being so myopic about what constitutes support or aid in combat and in combat operations.
There is more to winning a war and having the upper hand than just tanks and artillery.
The entire coalition from the first Gulf War would have fallen apart had we let Israel into the mix.
And they tried too. After the first Scud missiles fell in Tel Aviv...the Israeli Air Force launched F-16 for a counter strike...the U.S. refused to give them the IFF squawk codes that would have prevented them from getting shot down.
Why? Because the Arab nations who were ready to go to war to liberate Kuwait would have packed up their gear and left and prepared to instead fight Israel.
