On "Special Report" tonight, Charles Krauthammer discussed the tragic shootings in Chattanooga, Tennessee.

Four Marines were killed today when a gunman opened fire at two separate military centers. 

A police officer was also wounded and suffered non-life threatening injuries. The suspected shooter has been ID'd as 24-year-old Muhammad Youssef Abdulazeez.

The names of the Marines who were reportedly shot were not immediately released pending notification of their families.

Krauthammer said that today's shooting is "in all probability an example of radical Islam at work" in America. 

"The general issue is radical Islam," he stated.

He said that when Obama called the shooter a "lone gunman" earlier at his press conference, he "disconnected the dots."

"I think it's sort of the whole six and a half years of Obama always wanting to err on the side of downplaying the threat. The threat is radical Islam, which he won't say," Krauthammer said. "The war is going to be generational."
