First of all, I want Pakistan also involved because it is our duty to fight against the extremists and also because it would make the idea of war against ISIS more popular. Most religious extremists have gained great support because they tell recruits that the Christian West is killing fighters and occupying their country. If a coalition of countries which are predominantly Muslim are participating in the war against ISIS, what could extremist groups say?
What do you think they'll say? I'll give you a hint. Pakistan is fighting TTP - and what do those fellows tell their cadre about that? They say that the Pakistani govt is a poodle of America, and waging war on muslims at USA's behest. That's precisely what ISIS will tell their flock too. Every religiously motivated terror group claims to be the defenders of the religion, and anybody opposing them to be kafirs or allies of kafirs. One Pakistani admirer of TTP on this forum keeps calling MUsharaff as a "tout of kufr" for warring against talibanies on USA's order.
As of now, everybody fighting the ISIS are muslims. Whether it is Syrians, or Kurds. And yet that hasn't made them doubt for a moment that they are the true islamic heroes. If Pakistan gets involved in fighting against them, they will simply see the Pakistani state as a roadblock to the real rule of islam.
Iraqis are fighting. I understand there is a very little chance of a regional coalition. I am still distrustful of the American intentions. The last time they entered Iraq, they left it in ruins and sectarian violence was a greater problem then before. Before that, they were arming Saddam themselves with chemical weapons. If you do research, you'll find out CIA was involved in the coup which brought him into power. I do not trust them. I guess the ugly truth is, the US will be involved, but I am highly against it and deeply lament the future.
I don't know about the CIA being involved in Saddam's coup, but I agree with the rest of it. USA should not have warred against Iraq in 2003. Them removing Saddam from power and disbanding the Iraqi army set the stage for groups like ISIS to take over. They also created the power vacuum that ISIS exploited.
But as I asked before, if only the USA or NATO can crush ISIS, shouldn't we prefer them doing it, than to nobody doing it? A regional coalition against ISIS is not going to happen - everybody in the region are more interested in their own self interest. Shouldn't the removal of ISIS be first on our wishlist, no matter who does it?
