I'm sure most have by now seen the horrific news of what ISIS did to that poor Jordanian pilot. They are scum, the worst Iv'e seen in my lifetime. Unfortunately I see no alternative but for us, the West to destroy them, I don't think Arab countries will do anything about them, apart from maybe Jordan.
The argument goes that its not up to us to sort out middle eastern problems, especially after the previous Iraq war. However I feel ISIS threatens the West, terrorist plots are being discovered all the time, what will they be capable of if they grow any stronger? 9/11 type attacks? who knows.
Air Strikes are not enough, we need numerous countries, UK, US, Jordan, etc to send in troops and completely overrun and destroy them. Its disgraceful what they are getting away with. I think this war is far more justified than the previous Iraq war.
