BBC News reports that “If Britain votes to leave the European Union it could have a negative impact on the Nato alliance, a senior US military commander has warned.”  

“Lt-Gen Ben Hodges, head of the US Army in Europe, said he was ‘worried’ the EU could unravel just when it needed to stand up to Russia.”  

“He acknowledged the vote was a matter for the British people, but said he was concerned about the outcome.”
