The solution is plainly obvious. Its a small country. You militarily blockade them, close them off from the internet and all commerece, forbid their citizens from traveling, and freeze the assets of any industrialists who support their cause, and you trade more with their enemies. The regime would collapse pretty quickly since the region is in no way self supporting. And theres not much they can do about it that they arent already doing anyway. Then you leave them that way for a decade or two while their wealth and influence fades to zero. Problem solved. And if they use their nukes you turn every one of them to glass.

Zionists are a miniscule percentage of the human race. We might take some losses getting them under control but if we dont do it we'll pay the losses on a continual basis anyway. Its past time we rip the bandaid off and do the needful.
