Since October 30 2021 the U.S. is warning of a Russian military buildup and a potential invasion of the Ukraine.
Over the last days the screaming over Russian exercises on Russian grounds has again increased. The U.S. Secretary of State and the Secretary of Defense have both called their Russian counterparts. President Biden will later today call President Putin.
But if the situation is really as dire as the U.S. claims why is it doing this (machine translation)?
An American submarine entered Russian territorial waters in the Kuriles region, and special means were used against it, the Ministry of Defense said.
"On February 12, 2022, at 10:40 Moscow time, a U.S. Navy submarine of the Virginia type was discovered in the area of the planned exercise of the Pacific Fleet forces in the territorial waters of the Russian Federation near Urup Island of the Kuril Ridge," the agency said.
The crew of the submarine was given a message in Russian and English via underwater communication: "You are in the territorial waters of Russia. Surface immediately!"
The foreign warship ignored the demand.
"In accordance with the guidelines for the protection of the state border of the Russian Federation in the underwater environment, the crew of the Pacific Fleet frigate Marshal Shaposhnikov used appropriate means," the message says.
The American submarine used a self-propelled simulator to double the target on radar and acoustic control means and left Russian territorial waters at maximum speed.
A detachment of ships of the Pacific Fleet continues exercises and controls the underwater environment to prevent violation of the state border.
In connection with the incident, the Defense Ministry called the military attache at the US Embassy in Moscow.
The Kuril islands are north east of Japan and part of Russia
During the Yalta conference on February 11 1945 U.S. President Roosevelt had conceded the Kuril islands, then completely under Japanese control, to the Soviet Union in exchange for the Soviet Union joining the war against Japan.
