I don't think they can reform Islam to make it into some tolerant kind of religion --- they need to just face that and work on ways to convert out --- right now they can't convert into better religions because the others would kill them --- that's what the Koran instructs them to do with those who would leave Islam. In reality, it's a death penatly against any who criticize in any way the mullahs and imans or Islam --- there is no freedom of thought.
Warlike religions reform when they learn that war does not avail. A complete and utter defeat of the Islamists is, paradoxically the kindest thing we can do for the Muslims, as well as a necessity for our own preservation.
Individual muslims might convert out, but the vast majority are islemmings, heading for a sea cliff.
