NATO is set to conduct large-scale war games in the Baltics, involving 15,000 troops from 14 countries, including non-NATO members. The exercises will take place just 40 miles from a Russian military base, likely escalating tensions with Moscow. The drills will simulate a Russian invasion and are among the largest in the Baltics since the fall of the USSR. The exercises will overlap with two major NATO and allied military drills currently being held in the region. The war games come as American lawmakers move ahead on a massive $40 billion aid package for Kiev, around half of which will be devoted to arms shipments.
