Choosing the side of Muslims over the Jews would not be a smart move for a Christian. God is not neutral.
Lets not forget this started as a topic about questioning aid to Israel.
2 Chronicles 19:2 And Jehu the son of Hanani the seer went out to meet him, and said to king Jehoshaphat, Shouldest thou help the ungodly, and love them that hate the LORD? therefore is wrath upon thee from before the LORD.
Prophecy also showed the fate of the Islamic kingdom. That was fulfilled when the Caliphate was abolished after WWI.
So was God taking a nap when Hadrian annihilated Israel? Or perhaps upset about a recent event?
