The mullahs don't trust the traditional armed forces of Eran, which is why they have made the IRGC the US Marines of that country that have air, sea and surface assets and fighting capability.
ofc you can assume the top Generols of their armed forces are mullah loyalists but what about the officers and troops under them
Now what happens when these loyalist jernails are all killed
I think the Jews want to cause a Civil War in Iran with a portion of the Irani armed forces splitting off and giving #PhullSapport to the rebels, and this is also why Paapistan is being pampered by the US, to provide military support and logistics.
