I think you misunderstand Isreals role in the region, as far as US politics is concerned. As long as Isreal is a viable force in the region, They are seen as a knife at the collective Arab/Iranian/Egyptian throat. They act as a US proxy providing a counter weight to other regional powers. I'm no defender of Isreal, there actions, or Netanyahu, just providing another point of view.
Yes, but equal crimes deserve equal treatment. If it's not ok for Teixeira to be released, then Trump, under indictment for similar crimes, should face the same pretrial detention.
