I am afraid that this conflict will not end till Isis is destroyed it's because Isis will never surrender kind of like the Japanese in WWII
Indeed, sometimes you just have to kill them all, and the world needs to do that soon.
All those women these monsters are enslaving and mass raping, they are not doing it just for pleasure, they are using those poor women as breeding stock effectively.
There are probably already many hundreds or even thousands of ISIS babies.
The world needs to rescue those children before their young, innocent minds are forever tainted and corrupted by the foul ideology and brainwashing of these savages. Or else in a few years, the world will be confronted with the terrible reality of massed ranks of ISIS child soldiers and suicide bombers.
Facing with that, even the most battle hardened veterans will have their moral and willpower sourly tested, and many brave soldiers will unfortunately loose their lives as ISIS uses their very own decency, kindness and humanity against them.
Soldiers will run to the rescue of "injured" children only to be shot at point blank range or blown up by the very children they risk all to save.
Guards will hesitate and bulk as a wave of tiny children rush their checkpoints and not be able to bring themselves to gun them down even if they know those children to be strapped with explosives.
It will be worse when eventually, reluctantly, soldiers force themselves to kill children to save themselves and their comrades. The psychological damage from that will be profound, and make the crippling PTSD many veterans currently suffer seem like a good mood.
Many good men and women will have their lives destroyed by the experience even if they survive the battle, and some will be so stripped of their humanity by it, they may end up little different from the ISIS monsters they fought.
I am convinced that is what ISIS has planned, and we really need to act before we are faced with the reality of that nightmare.
