Washington (CNN) - President Barack Obama has responded to critics who disagree with his handling of the situation in Syria, saying he's more concerned about the end goal - no chemical weapons in Syria - than about "style points."
In an interview that aired Sunday on ABC's "This Week," Obama downplayed the controversy over Vladimir Putin's opinion piece in The New York Times last week, saying "this is not a Cold War" and that he welcomes the Russian president's involvement in the issue.

As for the public perception of his own management of the U.S. response to the alleged use of chemical weapons by the Syrian regime, Obama said, "Folks here in Washington like to grade on style."
"And so had we rolled out something that was very smooth and disciplined and linear - they would have graded it well, even if it was a disastrous policy," he continued. "We know that, 'cause that's exactly how they graded the Iraq War - until it ended up… blowing up in our face."
Asked by ABC's George Stephanopoulos whether the recent events changed his view of former President George W. Bush, Obama said, "No, no. What it says is that I'm less concerned about style points. I'm much more concerned about getting the policy right."
Obama got some of his most candid criticism last week from an ally, Republican Sen. Bob Corker. The senator told CNN's Dana Bash that the president has lost his credibility and is "very uncomfortable being commander in chief."
And following a deal reached between the U.S. and Russia on Saturday for Syria to hand over its chemical weapons to international control, two Republican members of the Senate Armed Services Committee, Sens. John McCain and Lindsey Graham, said the Syria deal "does nothing to resolve the real problem in Syria" and allows Syrian President Bashar al-Assad to "go on slaughtering innocent civilians and destabilizing the Middle East."
Talking about his relationship with Putin, Obama said he doesn't think his Russian counterpart "has the same values that we do" and that Putin has a "different attitude about the Assad regime." But, he said, both countries "have an interest in preventing chaos" and "preventing terrorism."
"This is not a contest between the United States and Russia. I mean, the fact of the matter is that if Russia wants to have some influence in Syria post-Assad, that doesn't hurt our interests," he said.
"And I think there's a way for Mr. Putin, despite me and him having a whole lot of differences, to play an important role in that," he continued. "And so I welcome him being involved. I welcome him saying, 'I will take responsibility for pushing my client, the Assad regime, to deal with these chemical weapons.'"
On Iran, Obama said recent negotiations over Syria could still deter Tehran from building nuclear weapons, even though the U.S. did not use force to address the chemical weapons crisis in Syria.
The president confirmed that he and the new Iranian president, Hassan Rouhani, have communicated indirectly through letters. Obama believes Iran understands that the nuclear issue is far more significant to U.S. security interests than are chemical weapons in Syria.
"A nuclear arms race in the region is something that would be profoundly destabilizing," he said. "And so I - my suspicion is that the Iranians recognize they shouldn't draw a lesson that we haven't struck to think we won't strike Iran. On the other hand … what they should draw from this lesson is that there is the potential of resolving these issues diplomatically."
"Negotiations with the Iranians is always difficult. I think this new president is not going to suddenly make it easy," he added. "But you know, my view is that if you have both a credible threat of force, combined with a rigorous diplomatic effort, that in fact you can strike a deal."
