What powder keg? The hegemonic superpower guaranteeing Israel, the limited assets it even has in the area, is enough to completely hold off any kind of retaliation on behalf of Israel.

There won't be real consequences for Israel that aren't cancelled out by their gains in doing stunts like this. It's not fair. It's garbage. It's terrible.
Also reality.
