U.S. President Barack Obama showered fulsome praise on the U.S. Navy SEAL commandos who took part in the pre-dawn swoop in Pakistan on Monday that killed the country's most wanted terror ring leader Osama Bin Laden.

“I came here for a simple reason: to say thank you ... On behalf of all Americans and people around the world --- Job well done,” the President told the helicopter pilots and SEALs at Fort Campbell, Kentucky.

“Thanks to the incredible skill and courage of countless individuals, intelligence, military, over many years, the terrorist leader who struck our nation on 9/11 will never threaten America again,” said Obama.

The president said the operation to kill Bin Laden was one of the greatest intelligence operations in the country's history.

Obama also used the occasion to champion the success of the counter terror strategy of the U.S. government. He said the killing of Bin Laden was the greatest proof to the success of the U.S. strategy in Afghanistan. “Because of your service, because of your sacrifices, we’re making progress in Afghanistan ... In key regions, we’ve seized the momentum,” Obama said.
