NATO eyes changes at July summit after attack blamed on Russia - Welt am Sonntag

BERLIN (Reuters) - NATO must improve its defensive capabilities and willingness to act in the wake of increasingly aggressive and unpredictable actions by Russia, the head of the transatlantic alliance said in a German newspaper interview published on Sunday.

NATO Secretary-General Jens Stoltenberg said he expected German Chancellor Angela Merkel and other NATO leaders to revamp their approach at the next NATO summit this summer, given a risk that Russia could gradually give more weight to nuclear weapons in its doctrine, exercises and new military capabilities.
