Oklahoma Republican Sen. James Inhofe warned that the Islamic State is looking to attack a “major U.S. city,” as he urged President Obama to adopt a more aggressive policy.

Inhofe spoke to Fox 25 in Oklahoma City about his concerns with the growing terror organization in Iraq and Syria.

“We're in the most dangerous position we've ever been in as a nation,” Inhofe reportedly said.

He spoke after militants posted a video this week showing them executing American journalist James Foley.

“ISIS, they are really bad terrorists, they're so bad even Al Qaeda is afraid of them,” Inhofe told Fox 25. “They're crazy out there and they're rapidly developing a method of blowing up a major U.S. city and people just can't believe that's happening.”
