Policy Exchange was delighted to welcome Hon James Mattis, US Secretary of Defense, to our offices today. Secretary Mattis discussed the current global situation, a situation which includes the threats posed by North Korea and a Russia seeking to challenge the territorial integrity of its neighbours. He also spoke of the enduring importance of the UK–US Alliance and of Britain’s continued moral voice on the world stage, as Policy Exchange argued for in The Cost of Doing Nothing. He also praised Policy Exchange’s record of thought leadership in making the case for a Global Britain’s continued commitment to NATO.
