War to the Muslim world isn't just killing and butchering. Some of it is demographic (like in Europe) and some of it is political.
That said, there are many Muslims who aren't behind this world war...but they are what one might call lukewarm Muslims (MINOs). OTOH, the true Quranic believers...
Hamas is a card that is all about to be burned out from this as I see it.
So either the Muslim world can choose to go to war now with Israel or let the card be burned. I think they don’t care enough about Gaza. They might raise all kinds of diplomatic drama on it, but they don’t have the will to stop Israel.
