ISIS, al-Qaeda, and whoever can do whatever they want.
If these terrorists are in tune with European and American politics, and I must believe they are, in France they know Hollande is a member of the Socialist and Radical Left Party. The political left isn't going to fight back. They're wimps. These muslim terror groups know that. Same with our Dear Leader and the Dems. Any attacks the political left might try will be so uncoordinated and inadequate it will be useless. As evidence, we see just how both mentally and physically weak the primitives are on a daily basis.
As a conservative, I hate it for those who are being killed and wounded and their family and loved ones. But as long as people are intent on electing a bunch of weak-kneed pols into office, this is only going to get worse.
