Oh yes they are!
How do you think the Israelis helped create Hamas? Because there was all kinds of violence between factions so the Israelis took the opportunity to cultivate a new group which turned out be Hamas---it backfired spectacularly against Israel, as we are witnessing today.
Just as there was Irish-on-Irish violence during 'the troubles'..
Just as there was 'black-on-black violence' during the apartheid days..
Dude, no group is immune to this shit😔😟..
Now apologize before I set Hamas on your backside!!
