Because Iran knows if they get involved, Israel will annihilate them.
Yep, they are finishing off Hamas quite easily.
Give Iran their due. Israel has no way to reach them. No carriers. No air space agreements. And they’re far far up a narrow waterway. If Obama hadn’t publicly exposed the airfield in Khazakhstan, or was it Azerbaijan?, we might have used that. But noooooo!
So if Iran wants to mix it in, it’ll have to be via Lebanon or Syria. The local Shiite notables in Iraq, Ali Sistani and his boy sidekick with the middle-aged paunch Muqtada alSadir, are not with Iran, and have been fighting Iran’s influence, last I heard.
