CW: Worst mistake?
Obama: Probably failing to plan for the day after, what I think was the right thing to do, in intervening in Libya.
From the article you just posted, I clicked the link to read what he actually said, and I read it as he expressed regret for not intervening more!
It’s like criminals expressing regret for getting caught.
Yeah, I think he didn’t want to leave Libya in the mess it was in. That’s my assessment at a glance.
