"Secretary Carter emphasized that the United States and the United Kingdom will always enjoy a special relationship," Cook stated. "Secretary Carter welcomed Minister Fallon’s commitment to continuing the United Kingdom’s active and enduring role in global security issues, in particular its work within NATO and efforts to accelerate the lasting defeat of ISIL [Islamic State]."
Carter has no doubt that the United Kingdom will remain a reliable NATO ally following Brexit.
“The Secretary [Carter] is confident that Britain remains a stalwart ally, a NATO ally of course, and that the NATO alliance itself will be able to address this particular situation," Cook stated when asked if NATO could be weakened post-Brexit.
Moreover, the US Department of Defense will work with its counterparts in London and Brussels to resolve any issues between the two countries following the UK decision to exit the European Union.
"We’ll do whatever we need to make sure that relationship — both with the United Kingdom and European Union — remains as strong as possible, but there are clearly issues they need to resolve themselves in terms of commitments that the United Kingdom has to the European Union and in that part of the world," Cook told reporters.
