Israel is the biggest recipient of US military and other foreign aid.
If they 'bought' those, it was with US $$ given it to them by the US government, and that would have been in addition to the steady stream of top notch weapons not only already given to them, but that Biden increased to help Israel genocide the Palestinians away.
But you already know this. In fact, we both know you can write volumes on this, down to the exact weapon models and numbers shipped.
