Why can't Trump stop the Gaza genocide?

I wonder what the plan is for [ending the Gaza genocide]. Trump's Iranian action was such that Congress, which is controlled by Israel/the deep state, couldn't complain. 

Even though it ended a war, they probably wanted it to be another 20-year war. 

I don't think Trump can send troops in to Gaza without Congressional and therefore Israel's approval. 

The same is true for stopping military aid. 

I'm not sure what option is open to Trump to stop the humanitarian disaster there. 

Not while Congress is owned by Israel, and Israel's Mossad kills anyone who goes against them. 

That's why Israel is so tricky to deal with. 

Similarly, Ukraine, who are being controlled by European countries and other deep state entities who want the war to continue until there are no Ukrainians left, or they run out of money, just to hurt Russia. 

The US should definitely stop all support for Ukraine. 

But once again, Congress, who are deep state controlled, wouldn't allow it.
