War on terror

Corker looks to next front in war on terror

The reports delivered to U.S. Sen. Bob Corker and other lawmakers last week were blunt in their assessment of the fight against the Islamic state extremists and terrorism.

The ideology of IS echoes Nazism in its genocidal ambitions and tone, one counterterrorism expert warned. Last month's bombings in Brussels leave no doubt that the threat IS poses to the West is far greater than anticipated, concluded another.

The potential for an IS-directed attack in the U.S. is real and could be similar to the massacres that killed dozens in Brussels and Paris, predicted yet another.

Corker, the Chattanooga Republican who chairs the Senate Foreign Relations Committee, said the warnings underscore what U.S. officials have long known would be a prolonged battle against IS and terrorism.
