If the argument is that the United States shouldn't be a global power, that it should dismantle the US military and be a demure, multilateral player in the international space, sure, attack NATO. However, attacking NATO while saying the US should be a stronger international player is contradictory.
People get angry about the Israel aid not because of the volume of funding, but because of the human rights/colonialism problems that the US subsidizes. I personally feel that way, but at the same time I understand the realpolitik deal with Israel - I believe the purpose of keeping Israel there is to prevent some version of the Ottoman Empire from re-forming.
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?

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.
