==Different western powers have tried to use Islamic viciousness, but it has always come back to bite them.
Yep, and the Russian Communists (including Putin et al) have been using it from at least 1916 until the present day. They need to be called to account for this.
Well, in all fairness, we tried to use them, too. Of course, so did the Spanish kings 1300 years ago (when they called on the notoriously vicious Muslims in a regional war) and all they got for their money was having their kingdoms taken over and then being killed. I think Russia is experiencing the same thing right now.
The lesson is that there are some critters so vicious the only thing you can do with them is put them down. You sure can't make alliances with them.
