We can argue whether the present-day Islamic fascists have the military means comparable to what was had in the past by Nazis, Fascists, and militarists — I think a dirty bomb is worth the entire Luftwaffe, one nuclear missile all the striking power of the Japanese imperial Navy — but there should be no argument over who they are and what they want. They are fascists of an Islamic sort, pure and simple.
And the least we can do is to call them that: after all, they earned it.
Oh, and then kill the fascists. That, in fact, is the least we can do. They've earned it.
