Rush Limbaugh appeared on "Fox News Sunday," saying the president's dealing with ISIS is "inept and incompetent and nonexistent."
The conservative radio host told Chris Wallace that it seems like the President's "link to Iran and Syria" is preventing him from taking bold action in the Middle East.
"I don't like saying any of this," he said, "but it's obvious that Obama is very sensitive to Iran's needs and is trying to satisfy them," referring to the lifting of sanctions as part of the nuclear deal.
Limbaugh said that, if he were in charge, he'd strike the terror group's oil assets -- their tankers, wells and depots -- regardless of the civilian lives that might be in the way.
"That's their primary source of revenue. I would hit that and I wouldn't care," he said.
"You know, Chris, the world is governed by the aggressive use of force. And the purpose of war, and the purpose of military, is to kill people and break things. That's how you win. And you keep doing that until the other side says 'I'm sorry,' and surrenders."
"Barack Obama's number one enemy is the Republican party and the conservative movement," he added.
