> I believe the purpose of keeping Israel there

Here's part of the problem. Does it make sense to you Israel just disappears? Sounds like it from what you're saying. Isn't it weird though - how many nation states do you think should vanish?

> but because of the human rights/colonialism problems

If Western societies really wanted the conflict to dissolve they wouldn't keep encouraging the Palestinians to "return" to their home (75 years after). Western societies keep the conflict alive. So it makes me think human rights issues isn't really the thing here.
