Sure Islam can change... It can convert to Christianity.
wishful thinking...
that would be my most basic desire, that they would embrace God's Grace in Christ and get out of the works, indeed terrible works, that mad mo deceived them with.
then there would be no need to have these battles ... and they would learn the New Testament love for the Jews (Romans 11:25-29). What percentage will abandon it after all they have seen, I do not know.
But, this will not happen until the Lord Himself has returned, and of His Kingdom there shall be no end. Amen.
