I highly doubt that israel the country wanted this turn of events, for the simple reason they are not stupid and the cost-benefit ratio of this seems bad for them.
They won’t want to be seen as reining in Israeli military overreach because there’s a feeder pipeline from the Israeli military into both politics and the weapons industry. It’s the same people running the country that are selling these weapons.
Well… obviously? How else could Israel treat him?
Yes and sort of and no.
The thing with weapons is that occasionally you sell them to people you end up fighting. Take the Falklands war - Argentina was using American, French, and British weapons to fight the British. It happens, it's a bit of egg on everyone's face, but it is what it is.
When you're a major arms dealer, you'll eventually end up selling guns to an enemy of your ally, or supposed ally.
