For anyone who has worked in Israel or who has just visited it, there is no doubt that Israel is one of the richest countries and it has more than enough of its own resources to ensure that it maintains its military superiority against any neighbors.

Israel certainly does not need a permanent aid for that, though of course they would be fools to refuse the many billions of $ they receive as a gift from USA.

Perhaps this aid might have been justified in the initial years after WWII, but it has been a long time since the initial reason cannot have remained true.

Now USA claims that it may have not obtained benefits commensurate to its expenses in the relations with many other countries, even if it is much less clear which were the benefits obtained by USA for paying this aid to Israel every year.

A part of the money paid to Israel is likely to return to some US companies that are friendly to the US government, so this is an indirect method for giving gifts to those companies too, but in other countries USA has been able to obtain such profitable contracts for well-connected US companies in a much cheaper way, just by bribing or blackmailing the local governments, instead of paying the contracts in full with US money.
