NATO’s response to the new threats has been the biggest overhaul of its command structure in a generation. Two new headquarters, one focused on the Atlantic, based in America, and another on logistics, in Germany, will be established over the next three years, adding 1,200 personnel. Generals are also getting chummy with Eurocrats. EU-NATO relations were once “trench warfare”, says Sir Adam Thomson, Britain’s envoy to NATO from 2014 to 2016. Now there is “unprecedented practical collaboration”. The EU published its own action plan on military mobility in March and sent the head of its military staff on a joint tour of Washington with his NATO counterpart last week.
