Okay, let us dissect this. First: Courage or not, land war or not. If the they believe they're in a war, then war rule applies. Second: read the verses in surat alNisa'a. They don't have to be in a battle situation. They only need to be in ready situation. Third, same goes for second. Not sure how's this a different argument. Fourth, from a strict Fiqh stand point, you can do Tawaf in your shoes given they're clean; the holiest of holy places. Wearing shoes or not is not something that is specifically prohibited, it's always a matter of cleanliness and has nothing to do with respect. Same goes with your clothes, you can wear them to pray as long as they're clean and covering. The habit/tradition of taking of your shoes in mosques comes from the fact that they're most likely filthy, and it's tedious to keep cleaning or cleaning after them. Simplify Sharia, don't make it mysterious or mystical. Having said that, I'm only talking Fiqh points to clarify this side issue. Whether they're in a just war or not, or whether they're traitors or not, that's a different issue. I will not delve into their intentions as to I would never pretend to know them. دعهم لربهم يتولاهم..
