Since there can be no reinterpretation of the Koran, no reformation movement is possible (cannot remove the passages that encourage holy war against Jews Christians and infidel).
The REAL reformation for muslims can only come from rejecting Mohammed's rewritten Judeo-Christian Bible (the Koran) and returning to the original text.
I won't be so bold as to believe that all muslims would become Christians (they have been brought up to see Jesus as a man, not divine, and to not believe in His death and resurrection for our sins). Muslims COULD become Jews but we all know how much internal torment THAT decision would give them.
Ahh, but there is a secret weapon: the Koran. As the Koran states, he who appostates (willingly or not) will be given one chance to reconvert. Any who appostates a second time is given no more chances to reconvert and must be put to death by being crushed by horses.
