I think Barak Obama's speech could possibly be read as a message to Cameron, Hollande and the like that they needn't wave for his attention when they need U.S. Military equipment to engage islamist rebels in places like Mali.
That said, I do think that under the Global circumstances, it was tempting fate just a tad to smile like a "MAD" cartoon character and announce without the slightest hint of caution, such a bold prediction for the future.
