NATO's recent war games exercises throughout the Atlantic, Europe and Black Sea regions are raising concerns with Russia, though NATO officials say the exercises aren't aimed at Russia.
The war games are being referred to as Steadfast Defender 21, and are a test of NATO's military response to an attack on any one of its 30 member states, the Associated Press reported. The main focus of the exercises now is testing NATO's ability to deploy troops from America and maintain open supply lines.
Russia's increased military presence at the border area with Ukraine has caused NATO reason for alarm, and tensions in Ukraine have heightened. In 2014, NATO launched one of its biggest defense spending initiatives following Russia's military annexing Ukraine's Crimean Peninsula. There has been an increase in NATO activity in countries neighboring Russia, including Estonia.
The top brass at NATO deny the exercises involving around 9,000 troops, several warships and dozens of aircrafts are specifically aimed at Russia. Regardless, the games have been focusing on the Black Sea, where Russia has been accused of blocking ships.

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.
NATO Secretary-General Jens Stoltenberg says the exercises send an important message to any potential adversary: "NATO is ready."
"NATO is there to defend all our allies, and this exercise sends a message about our ability to transport a large number of troops, equipment across the Atlantic, across Europe and also to project maritime power," Stoltenberg told The Associated Press aboard a British aircraft carrier off the coast of Portugal.
The ship, the HMS Queen Elizabeth, is the pride of the British Navy. It's making its maiden voyage and carrying 18 F-35 jets: the first ever deployment of so many of the 5th generation planes aboard an aircraft carrier.
The ship's presence, part of a 6-7 month deployment that will take it south past India, through Southeast Asia to the Philippines Sea, is aimed in part at restoring Britain's tarnished image as a major global power since it left the European Union.
Adorned with high-tech U.S. jets and flanked by warships from other NATO countries, the carrier strike force also stands as an important symbol of unity as the world's biggest security organization tries to recover from four tumultuous years under the Trump administration.
Stoltenberg will chair a NATO summit in Brussels on June 14 with current U.S. President Joe Biden and his counterparts keen to usher in a new era of trans-Atlantic cooperation, as troops leave its longest-ever mission in Afghanistan while tensions with Russia, and increasingly China, mount.
The war games tie in two new NATO command centers, one in Norfolk, Virginia; the other in Ulm, Germany. Part of the focus of its first phase was to protect the undersea cables that carry masses of commercial and communications data between the U.S. and Europe.
NATO says Russia is mapping the cables' routing and might have darker intentions.
"We all lulled ourselves into thinking that the Atlantic was a benign region in which there was not anything bad going on, and we could just use it as a free highway," Norfolk's commander, U.S. Navy Vice-Admiral Andrew Lewis said.
"There are nations are out there mapping those cables. They may be doing something else bad. We have to be aware of that and answer that," he told reporters.
NATO says its policy toward Russia is based on two pillars: strong military deterrence and dialogue. But high-level meetings between the two historic foes are rare, and European officials insist that President Vladimir Putin is turning increasingly authoritarian and distancing himself from the West.
"We're ready to sit down with Russia, because we think it's important to talk, especially when times are difficult," Stoltenberg said. "The main challenge now is that Russia has not responded positively to our invitation, or our initiative, for a meeting of the NATO-Russia Council," their top consultative forum.
