Israel has almost no industry to speak of, except tourism. Where does Israel get all its money to have the 5th most sophisticated army in the world? Well, for starters, read this:

"An American team will land in Israel in July to finalize the deal. Israel currently receives an annual $2.4 billion in military aid."
It's a pretty sweet setup. America gives military aid to Israel, in return, Israel develops new weapons and promises to buy American weapons and test them in the field of battle. The military aid is only half the picture. Then there are "loan guarantees":

The Bush administration announced Tuesday night that it will trim $289.5 million from a $9 billion package of loan guarantees for Israel,
What's a loan guarantee? Its a low interest loan that also gets refinanced on a regular basis, and is a guaranteed annual source of funding to the Jewish state.
Israel is America's most favored satellite state. No two other countries on earth share such a codependent relationship, with one being funded to do whatever it pleases while the other enjoys its extension of power through it.
Lastly, this business about America's isolationist policy you speak of is just propaganda garbage pushed out by American governments. It has always been intensely interested in world affairs, and has been a strategic player in positioning itself for becoming and maintaining its superpower status. Successive American governments tell its citizens and the world that it is "isolationist" so as to pretend it has no such interest, that's all.
Your arrogant remark to Nina is really undeserved, particularly when you speak from ignorance.
