I agree too with RR.
As a late teenager, we all went into Bimingham town center the very next evening after IRA bombers has blown up 3 pubs. It was an act of defiance, and respect for one of our group who lost his life with his soon to be wife.
We cannot give in, but more, we should go after these criminals and shut them down.
The surprise that they bomb and destroy mosques is comparable with Protestants vs Catholics in NI, both purported to be Christian, but doing despicable and inhuman acts on each other.
It just proves to me that it's not a religious matter, they are opportunists, seizing the day. The U.S. and allies have destabilized an area of the planet that only someone like Saddam Hussain could control.
Don't get me wrong, he was bad, but at the same time he kept the lid on the place. Now it's like an open wound, and all manner of infections are breeding there and elsewhere, unchecked.
Sooner or later we (meaning the rest of the world including the middle eastern countries that have supported allied attacks on ISIS) have to crush them.
But leaving it later will only mean more headlines and heartache for innocents, before we get off our complacent arses.
