My post didn't ignore the militia surrounding Israel, it was mentioned on my original post.
The problem with it is that they all revolve Iran. But Iran probably would need Russia backing to have them attack Israel be it high or low intensity conflict. The issue here is, Israel is currently staying neutral in Ukraine, and if Russia F with Israel by letting Iran attack Israel themselves or using their proxies, that may change, unless you think those H - Group can eliminate Israel once and for all, if Israel remain, it have the capability to make Russia progress in Ukraine a living hell (Don't forget Ukraine have a very large Jewish population, include the president himself, Zelenskyy)
That is the reason why 9 months down, and we are talking about IDF attacking the last strong hold in Gaza, and none of the H-Group have done anything meaningful. If there were things to be done, they would have done so already. We are talking about a total wipeout in Gaza here.
