Sen. John McCain (R-AZ) was as kind as he could be when he called President Obama's foreign policy "feckless" on Fox News Sunday.

McCain said the administration has failed in carving out a leadership role in the world thanks to Obama's "leading from behind" strategy. From how he handles Vladimir Putin to taking the troops out of Iraq, Obama consistently shows the world his weaknesses and inability to be a strong leader.

McCain said one of the main reasons that the U.S. is now dealing with a terrorist group like ISIS is because Obama pulled the troops and didn't leave a residual force behind in Iraq. "All of this could have been avoided," McCain said.

Here is his full statement:

The president has got to come forward with a cohesive, comprehensive strategy, not only in Iraq, but also in Ukraine, also in other parts of the world. This is an administration, which the kindest word I can use, is feckless -- where they have not outlined a role that the United States of America has to play and that's a leadership role.

No more leading from behind. No more don't do stupid stuff. No more tell Vladimir that I'm going to be more flexible if I am -- when I'm re-elected. The president has to understand that America must lead and when America hasn't, a lot of bad things happen. This is not like the earthquake in San Francisco -- all of this could have been avoided, like leaving a residual force behind in Iraq. And obviously the challenge is now much greater than it would have been when the president made the decision not to leave a residual force in Iraq, among other things.
