NATO's biggest military maneuvers since the Cold War began in Norway in a hypothetical scenario that involves restoring the Scandinavian country's sovereignty after an attack by a "fictitious aggressor.
Russia, which shares a border with Norway, was briefed by NATO on the Trident Juncture 2018 drill and invited to monitor it, but Moscow is still angered by the exercise. Russia's defence minister had warned that Moscow could be forced
to respond to increased NATO activity near its western border.
The wargames bring together around 50,000 personnel from all 29 NATO allies, plus partners Finland and Sweden. Around 65 vessels, 150 aircraft and 10,000 vehicles will also participate in the drill, which takes place in central and eastern Norway, the North Atlantic and the Baltic Sea. It will go on till November 7.
