Dittos on the crusade.
I know there are sharply divided opinions on this site about our proper relationship with Muslims. Let me preface my following remarks by saying that I'm a retired Army officer with a foreign area officer specialty & a Middle Eastern emphasis. During the Iranian Hostage Crisis back in the '80s I was a low-level advisor because of contacts I'd made with Iranians. Later, as I worked in the field, I developed other acquaintenceships with numerous Muslims, mostly Sunni but a few Shi'ite, whom in other circuмstances I would have called friends-- except that Muslims aren't allowed to have Jєωιѕн or Christian "friends".
Based on my experience, it is my strongly held belief that Islam is pervaded by an irrational hatred of Christianity, Christians, & Western civilization in general. Forced conversion at the point of a sword is a central tenet of Islam, & Mohammed was a military leader who set that example. Unlike Christianity, Islam was spread mainly by military conquest, & nowadays they feel that Christianity has unjustly replaced Islam as the default religion in much of the world. They'd like to reclaim their pre-eminent position, & can see no nonviolent way of doing so. Hence the doctrine that if you die killing infidels for Allah then in the afterlife you get 72 virgins.
Given the above, our only proper relationship with Islam is war. I was once banned from another site for saying that, because the mods thought I was advocating ethnic cleansing. What I'm advocating isn't ethnic & it isn't cleansing-- it's a measured response to acts of war committed by Muslims against the United States, & against Christianity.
