One of the most interesting things to come out of that conversation is O'Neill's assertion that he and his fellow SEALs thought that they were essentially going on a suicide mission.
Here's what O'Neill had to say:
"The more we trained on it, the more we realised this is going to be a one-way mission. We're going to go and we're not going to come back. We're going to die when the house blows up. We're going to die when he blows up or were going to be there too long and we'll get arrested by the Pakistanis and we're going to spend the rest of our short lives in Pakistan prison."
Fox News' Peter Doocy asked O'Neill what it was like to train for a mission he didn't think he would come back from. O'Neill was unequivocal.
"It was worth it because this is it. We would have moments where we would joke around and laugh and then it kind of hits you and you go, 'Alright, let's get serious again cause this is going to happen. Were not coming home ... No [it was not a sad feeling]. It was more of 'we're going to die eventually. This is a good way to go and it's worth it to kill him, because he's going to die with us.'"
