You misoverestimate the President. He lacks the conviction to follow through with a venture that requires genuine fortitude. No, that is not a cheap shot. It is a statement of fact. He does not believe that the US should ever assume a role wherein our role is definitive.
I don’t entirely disagree with him in principle, but in practice, in my opinion, his position is cowardly. We can not retreat from the world stage as policeman and expect the void to not be filled.
He will not go that far, as it requires a firm sense that our military leaderhsip is a suppressant of activity by other countries.
Whoever is elected will inherit a great many problems from Obama.
