While I agree that with a muslim superpower, islamic terrorism would disappear, I don't think the lack of muslim superpower is the reason why islamic terrorism exists. Being a terrorist is a very precarious career. Very few people want to be a terrorist. For terrorism to appear and sustain, you not only need hatred but also encouragement and support, particularly material support. The latter part seems to be a specialty of US, which helped create terrorist groups to wage proxy wars for them. The recent news from Ukraine show the increased practice of terrorism by the NATO-armed Ukrainians. It is an easy transition from being a Nazi to being a terrorist. Both attack civilians without remorse.
To motivate someone to kill themselves and others, you need to brainwash them that some great injustice is being committed and there is no one else to avenge it. The reason individual Christians or Jews don't go blowing themselves up around the world is because power countries pick up their cause and take offenders to task.
