I would go much further back than those two wars, simply put this is a situation that had been brewing for many years and simply got to where it was through better organization abilities of the groups and the withdrawing of forces to keep the peace. Our actions in Libya, Syria, and elsewhere, certainly have dug the hole deeper.

But lets be honest, go back to the Treaty of Sèvres and subsequent assigning of territory to European countries and how it was done without regard to the religious and ethnic traits of those living there. As in, European Colonialism started this mess as it did in Africa. This did not happen in the last twenty years, this is generation after generation finally reaching a point to where they could act.

If you keep arming all sides and leave it is to be expected.
