Yes, the Apology Tour, the leading from behind (an oxymoron), the shifting and farcical red lines, the premature withdrawal from Iraq thus squandering the success that the surge had brought about, etc., etc. really worked well, eh?

Obama was not a Harvard MBA grad (you're confusing him with George W. Bush who actually was an MBA grad).  He was a Harvard law grad and his marks are "strangely" considered a state secret as is the story of how he got into Harvard from Columbia.

You can choose to back a president and a foreign policy strategy based upon weakness and irresolution and amateurism if you wish.

But in my view this abominable Obama foreign policy led to further adventurism, destruction and danger for the US and the world including the rise of ISIS.

As Trump who unlike Obama is willing to be schooled by the best professionals available is finding out, withdrawing from global leadership cannot be an option for the US.

P.S. It takes critical thinking to become a billionaire.
