It's probably not unrelated to the fact that most of the people living in those countries happen to be Muslim.

Whereas in countries where a majority are Christians, conflicts tend to be fought mostly by... Christians. Eg Russia/Ukraine, many South American countries, even the events of the US Capitol on 6 Jan. Doubt there was a majority of Muslims "fighting like hell" that day. Not to mention both of the World Wars in the last century and a bit.

Meanwhile, there's places like Myanmar where, I'd feel fairly safe in betting that the majority of combatants in recent conflicts are Buddhists. As were those in Cambodia in the 70s. You could also even double up and consider the Vietnam war where Buddists and Christians were the actors.

So maybe it's just religion generally? Probably not though, since China's population is majority atheist, but that didn't help the students in Tiananmen Square any more than it helped Hong Kong.

The point is, humans in general have a seemingly neverending thirst for conflict, and not all of it can be lazily attributed to which religion they happen to be.

Perhaps right now there is more conflict in Islamic countries, but it wasn't always so and it won't always be so either. Snidely hinting that Islam is the problem is not helpful.
