The "I's" and "My's" were a way for him to convey that he personally, as the leader of the world's most powerful country, authorized the mission and to publicly declare to the world that he takes full responsibility for our illegal incursion into another country. No matter what happens, this operation doesn't even leave the ground unless the man in charge puts his ass on the line and says "do it".
If it had gone wrong, you and everyone else would be skewering him like a roasting pig on an open fire. He and he alone would be responsible if those men didn't make it back alive, and the sword cuts both ways. It went our way thankfully.
He did give credit to the intel people and the guys on the ground as well.
