This isn't High School. This isn't about being "fair" and treating everyone alike. This is doing what is in America's best interest. We treat countries differently all the time. If we have to muscle Israel a little to protect America, so be it. Israel would do exactly the same to us (in fact, it does).
Even Netanyahu thinks acting together right now is playing into the hands of the Arabs. He warned this weekend that the worst thing which could happen is for America's war on terror to become an America/Isreali war on Arabs.
We can't turn a switch and fight a war. We have 8 years of Clinton to fix. We have munitions expanded in Afghanstan to replace. A build up is needed before we go all out.
The Arabs don't want us to have that time. Neither do Democrats. Lieberman and Biden are urging action now because they know it will get messed up and they will have an issue. somthing they haven't had since 9/11.
