I can agree with most of your thoughts, however I think that if Israel were to be disarmed today, there would be no Israel tomorrow. I'm not much on international politics, however I can see that the USA wants to maintain a sort of 'status quo'
With Russia arming Syria for example, the USA is forced to act to preserve Syria's prey.
Yeah, I would have to agree with that. Well, maybe not about the USA's motivation for involvement in that region. If you ever do want to learn more about international politics in that region, to understand the USA's motivation/investment in the region, you have to go back to what happened between Britain, the US, and Iran in 1952-53, then follow history from there.
But yeah, I agree that Israel would be overthrown without the ability to defend itself. That's why I'm not advocating for the disarmament of Israel. What I am advocating for is accountability for the way Israel uses the support it receives. While I agree that Israel does need to defend itself from a real threat, I also think it's reductionist and naive to view Israel as being totally innocent, and only acting in self defense.
