Israel is essentially used as a money launderer for the US where they can by proxy aid the perpetuation of fascist regimes in Central and Southern America to keep a stranglehold over the Panama canal trade route, the oil there, and the rare earth metals including lithium which the US will grow increasingly dependant on as they transition into renewables. Israel has spent billions in arms and training for many of these military and paramilitary organisations that engage in such fun activities as mowing down people who they even vaguely suspect of unionising as well as massacring villages of indigenous tribes that happen to stand in the way of oil pipelines.
The US used to do this military aid themselves in the 60's through to the 80's but the PR has grown so bad that now they just give Israel billions in US taxpayer money to engage in it for them. The media is a lot easier to control in Israel.
