The White House says President Barack Obama has tried to apply the lessons from the 2011 intervention in Libya to other situations where he must decide whether to use military force.

Obama says in a “Fox News Sunday” interview that his worst mistake was “failing to plan for the day after” the intervention. He says he still feels the intervention was the right thing to do.

White House spokesman Josh Earnest says Obama believes more could and should have been done to fill the vacuum of power after dictator Moammar Gadhafi was toppled.

Earnest says there was need for urgent action to prevent violence and that Libya’s governing structures had deteriorated for decades. He says Obama is more inquisitive now about what will be required after he orders an intervention.
