Trump rewrites national security playbook as mass migration overtakes terrorism as top US threat

Trump administration's new National Security Strategy shifts focus from Middle East terrorism to Western Hemisphere threats, declaring mass migration the top security concern.

"The days in which the Middle East dominated American foreign policy in both long-term planning and day-to-day execution are thankfully over — not because the Middle East no longer matters, but because it is no longer the constant irritant, and potential source of imminent catastrophe, that it once was," the document says. 

"It is rather emerging as a place of partnership, friendship, and investment — a trend that should be welcomed and encouraged."
