At least from a national security standpoint, none of the problems the U.S. and U.K. face will become easier to solve if the U.K. is out of the E.U.; on the contrary, I fear that a 'Brexit' would only make our world even more dangerous and difficult to manage.

I had the privilege of serving in uniform with British forces in Cold War Europe, Bosnia, Iraq, Afghanistan, and the greater Middle East.

There is no question in my mind that a 'Brexit' would deal a significant blow to the E.U.'s strength and resilience at exactly the moment when the West is under attack from multiple directions.
