Would you give bullets to someone after watching them shoot a kid if it benefitted you?
It has nothing to do with it benefiting me - or specifically the US as the case with Israel goes, or even the party or the politician. As I tried to describe in my original comment, it is a strategic move for GLOBAL PEACE - not just the US. This is not only about US intervention, which it is clear you have a lot of thoughts about, but also about the ports and access to resources both in and out for all of the countries in that region, and militaries of all countries. And destroying our only allyship in that region (not just us, but the other countries that have maintained their stance with Israel), maintains the ability to keep a foothold in that region.
If someone just shot a child in front of me, would I give them bullets? If they controlled the only access to all of the resources (oil, water, food, etc) that would cause my other allies to die without during times of crisis, I would absolutely consider it. That does not mean it would come without limitations.
For you to still think this way after it being explained to you shows how shortsighted and limited you are thinking.
From the rest of your comments, it's clear that you are very interested in politics and learning a lot, which is good! And you've gotten to a lot of topics, also good. But it seems like you have gotten to the surface level issues and become very passionate about them and it's that way or the highway instead of looking any deeper.
