But if the US stopped all financial, military and political support of Israel today there would not be an Israel 10 years from now.
When people say stuff like this, I can never tell if they're for or against supporting Israel.
I'm against supporting Israel (and most other countries for that matter). They have been around long enough to stand on their own two feet. They don't need Uncle Sam propping them up any longer. I wouldn't be terribly upset if the US went extremely isolationist and stopped all foreign intervention/support unless there was a direct threat to US soil (and by that I mean the 50 states, not the vague "US interests"). Keep a handful of bases in strategic locations in countries we are friendly with in case crap hits the fan and send the remainder of our military home. Let the rest of the world fight their own fights and let them determine the outcome, so long as America isn't threatened. Forcing democracy in areas that aren't used to it is a horrible idea, people won't appreciate or want the same type of government we have unless they are willing to fight and die for it.
Israel was placed in a horrible location. As long as it exists there will be big problems in the Middle East and as long as we support them a lot of countries that are hotbeds for producing terrorists are going to hate us. A Jewish nation should have been placed in Germany or Italy - they lost WWII and wouldn't have been able to do a damn thing about having to surrender some of their land. I understand there were religious motives in Israel's placement, but long-term safety and stability should have taken priority. Perpetual warfare should have been an easily foreseeable outcome when Palestine was displaced for Israel and a Jewish nation was plopped down in the middle of a lot of Muslim countries. If we stopped supporting Israel and they managed to survive on their own, good for them. If not...oh well, it wouldn't be the first country to be conquered. Not meddling in affairs on the other side of the globe that have nothing to do with us would do a lot to reduce the risk of foreign terrorist attacks against the US, and at some point that should be the primary concern over playing world police.
