A serving SEAL Team member said: ‘Obama wasn’t in the field, at risk, carrying a gun. As president, at every turn he should be thanking the guys who put their lives on the line to do this. He does so in his official speeches because he speechwriters are smart.

‘But the more he tries to take the credit for it, the more the ground operators are saying, “Come on, man!” It really didn’t matter who was president. At the end of the day, they were going to go.’…

Mr Kyle added: ‘He’s trying to say that Romney wouldn’t have made the same call? Anyone who is patriotic to this country would have made that exact call, Democrat or Republican. Obama is taking more credit than he is due but it’s going to get him some pretty good mileage.’

A former intelligence official who was serving in the US government when bin Laden was killed said that the Obama administration knew about the al-Qaeda leader’s whereabouts in October 2010 but delayed taking action and risked letting him escape.

‘In the end, Obama was forced to make a decision and do it. He knew that if he didn’t do it the political risks in not taking action were huge. Mitt Romney would have made the call but he would have made it earlier – as would George W. Bush.’
