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.
