I mean Saudi Arabia also does all those things, most of them far better than Israel ever could due to geography, and at a far lower cost. If Isreal snapped out of existence tomorrow, between Saudi Arabia, Iraq, and Greece European and North American power projection in the Middle East and North Africa remains almost entirely unchanged.
Honestly the military benefits of supporting Isreal while real are definitely not as important as the domestic political benefits to the US, which is to say that the conservatives like Isreal because it provides a nice place to deport all the Jews to while also maintaining precedent for an enthnostate with race based citizenship, and the Democrats like it because they get a lot of gifts, friends, and in their minds potential voters, all for doing exactly what the conservatives want them to do.
