As Russia tensions simmer, NATO conducts massive war games

ABOARD HMS QUEEN ELIZABETH — As tensions with Russia simmer, thousands of NATO troops, several warships and dozens of aircraft are taking part in military exercises stretching across the Atlantic, through Europe and into the Black Sea region.

The war games, dubbed Steadfast Defender 21, are aimed at simulating the 30-nation military organization’s response to an attack on any one of its members. It will test NATO’s ability to deploy troops from America and keep supply lines open.

Already in recent years, the United States and its allies have deployed troops and equipment in Estonia, Latvia, Lithuania and Poland to try to reassure those members neighboring Russia that their partners will ride to the rescue should they come under attack.

Russia’s decision last month to send thousands of troops to the border area with Ukraine has raised concern at the military alliance, which launched one of its biggest ever defense spending initiatives after Russian troops annexed Ukraine’s Crimean Peninsula in 2014.
