NATO leaders are preparing to approve “major increases” in the number of forces positioned in Eastern European countries, deploying four new battle groups to Bulgaria, Hungary, Romania and Slovakia, according to NATO Secretary-General Jens Stoltenberg. “I expect leaders will agree to strengthen NATO’s posture in all domains, with major increases in the eastern part of the alliance on land, in the air and at sea,” Stoltenberg said during a press conference on Wednesday. Stoltenberg added that he expects NATO allies to “agree to provide additional support including cybersecurity assistance, as well as equipment to help Ukraine protect against chemical, biological, radiological and nuclear threats.”
