It seems that religions are similar, but one of them seems to have a bigger percentage of people with the mindset of taking up arms and doing something with them. ARE they actually doing it in the name of Allah? It all seems kinda far fetched to be basing it on religion, a lot of it will be simple territorialism (as in they want Westerners/other Muslims they don't like out of "their" provences). Either way, "they" do seem to be a warrior-type people who are easily capable of arming themselves and enough ammunition to keep the hate going...
A lot of islam comes from times of war so they have a lot of direct quotes from their prophet during those times and also have many hadith (basically a compilation of stories of what their prophet did during his lifetime) that are related to war and violence which make it easy for people to use the religion to manipulate young people in to fighting for them since young muslims are brought up being told that Islam is perfect.
Keep in mind though that muslims argue a lot on the genuinety of many of the hadiths and in what context the violent verses of the quran can be used.
