As an American, I abhor the idea of a religious state. We are a melting pot, and there's no official national religion (yet). I simply don't care about or support any other society other than ours — especially if it's a religious state or an apartheid state.
So let's get real here. There is only one moral and practical peaceful solution to the Palestine/Israel issue: a one-state solution for all of Israel and Palestine. The alternative is an endless continuation of historic and ongoing butchery, which will ultimately result in a genocide for one or both parties — or possibly world war.
If there were a one-state solution, many Israelis might wish to emigrate. Let them go.
