A ceasefire wont do, a ceasefire will just give Iran and Russia more time to resupply and regather their terrorists to attack again, all that on the back of the entire local population
Eradication of the terrorists and simultaneously helping the locals to become self sufficient and able to defend themselves and implementing education is a long-term solution for the terrorism problem
The law requires that i awnser anything but executions of the intruders... However i tend to be above the law.
At best put people from way outside in these organizations and ban religion within them, maybe ban Muslims in general, it would be the same with a Christian terrorism problem, you wouldn't hire Christians to solve that.
But UN is a waste of anything on earth, so they will likely exclusively hire islamists from Iran when they get involved. Thats why i hope Israel forces them out for good.
