President Barack Obama bears responsibility for everything that happened during his presidency, including the rise if ISIS, Sen. John McCain said Wednesday.

Responding to news of Obama’s authorization to send an additional 600 troops to Iraq, the Arizona Republican said, “This is the same country we had to remove our troops, by the way, in the words of Barack Obama: ‘the most democratic, free, prosperous Iraq in history.'”

McCain, who lost the 2008 presidential race to Obama, said earlier decisions by the president have led to the current conflict there against ISIS.

“Everybody was shocked when I said the president bears responsibility — he bears responsibility,” McCain said. “He’s the one that turned down the recommendation of [Gen.] David Petraeus, [former Defense Secretary Leon] Panetta, and [former Secretary of State] Hillary Clinton to arm and train the Free Syrian Army and establish a no-fly zone.”

The senator added that had that happened, the situation would be very different today.
