A 10-year-old boy whose firefighter dad died on 9/11 was thrilled to meet President Obama during yesterday’s wreath-laying ceremony, but that didn’t stop him from offering the commander in chief a critique of the raid that killed Osama bin Laden.

“He said, ‘How do you feel about Osama bin Laden being dead?’ ” Christopher Cannizzaro, who was just 10 months old on 9/11, recalled of his exchange with the president.

“I said he could have done something a little less harsh.”

But the Staten Island boy was beaming when Obama greeted him.

“It meant the world to me to meet the president,” he said.

Christopher fist-bumped Obama and handed him a prayer card bearing a photo of his father, Brian.

Brian Cannizzaro was a member of Ladder Co. 101 in Red Hook, Brooklyn.

Christopher’s mom, Jacqueline Cannizzaro-Hawkins, said Obama touched her son’s metal chain, which carried a photo of his hero dad.

“It was an amazing moment. He talked to my son. He said Christopher resembled his dad,” she said.

The Cannizzaros were among the four 9/11 families that Obama greeted during the wreath ceremony. Jacqueline said she put in a request with the Fire Department to be there.

“This renewed my faith in the country. People never forget 9/11 — especially the president,” she said. “I told the president, ‘Thank you. Thank you for seeing it through.’ And thank God for the Navy SEALs.”
