Israel is one of our closest allies, and with the current hodge-podge mixture of Israeli-Arab territories, a two-state solution is unfeasible.
The post-Yugoslav Balkans has been relatively stable. It was Milosevic that was the problem there; by declaring war on the constituent parts of Yugoslavia that declared independence (except Macedonia). Since he's gone, it's been stable.
I feel that the only way a unified Israeli/Palestinian state would work is to have a political structure similar to Northern Ireland. Although, I don't think it's for us to get involved in the internal political workings of other nations.
