How is what happens to another country on the other side of the world the business of the USA? Further, can the USA afford that? ...
I've never understood why so few people recognize that the US/Israel relationship isn't totally one-sided. Pretty much every major tech company has a significant presence there and a lot of non-trivial advances have specifically come from their Israeli HQs. The stuff to come out of Intel's branch there is particularly interesting (huge, major processor breakthroughs made thanks to the unorthodox approaches their employees came up with). Everything I've ever read on the topic cites their military, history of turmoil, political structure, % of population made up of immigrants, etc. for contributing heavily to an adaptive, unorthodox mentality that is extremely well-suited to innovation and entrepreneurship.
Obviously, that's just one part of a much larger issue - but there's a lot of value coming out of such a tiny nation.
