Is the murder of American Diplomats in Libya on the eleventh anniversary of 9/11/01 planned and intentional?

Yesterday, on the eleventh anniversary of the 09/11/01 attack on the US by Islamist terrorists, Islamists attacked two separate US facilities in two separate nations, Libya, located in North Africa and Egypt, located in the MIddle East, killing the US Ambassador and three members of his staff.

Is it even remotely possible that these near simultaneous attacks occurred far apart, in different nations, on this particular day of import in the US without malice aforethought and planning? How much responsibility must President Obama accept, having supported the overthrow of the Libyan and Egyptian regimes that were at least marginally pro-American?
