While these animals hack off the heads of American citizens, our president is enjoying his vacation, thinking "yea, we are doing a good job over there" bombing a few. Send in the dang Marines and end these people.
And what are you going to do different than Obama? Spew threats at Islam? Round up all Muslims and put them in internment camps.
What exactly is this magical foreign policy you are looking for, that you obviously think will make these terrorist zealots love us and stop trying to kill us?
Its obvious that obamas foreign policy in the ME that is to do the exact opposite of what bush did is a failure on every count. Its obvious that he should have addressed the war in Syria when it started instead of waiting for it to explode and create isis. And its obvious that the peace loving moderate muslims in the ME and across the globe are not going to lift a finger to stop the radicals and will allow them to continue on their rampage until the evil west stops them and then the moderate muslims can bitch about western intervention in the ME.
The Nazis, as evil as they were, had a secular leader, a Furher, telling them what to do. But ISIS is saying God Almighty is telling them to do this. That is much worse in my opinion. If you think the creator of the Universe is telling you to cut heads off.
If it's a religious component you'd like then I would point to the LRA which has been operating since 1986 (though it is pretty small scale now). With the ISIS we've seen massacres and persecutions done in "God's name." we've seen that with the LRA too, though the LRA have also used different tactics in terms of heavy child soldier usage, forcing children to rape their grandparents and kill their family so that even if they escape they will forever be shunned in their home community (goal is to cut down on defection), we've seen recruitment tactics from them that involve burning down a school and capturing those who make it out alive, the beheading, debreasting, and other forms of mutilation of entire villages with machetes and the mass rape of thousands.
I'd point also to the Liberian Civil War, the civil war in Sierra Leone, the DRC conflicts, the Rwandan Genocide, the Bosnian Genocide, the Genocide in Darfur, etc. There are plenty of examples of incredibly horrible and near incomprehensible human treatment of each other, particularly during conflict.
