I also suspect he needs to keep just a few on borders elsewhere just in case somebody has something else planned ….
WEEEEEEELLLLLLL
Funny you should say that....
Japan has made a point of declaring the Southern Kurils as their sovereign territory today. This isn't a new dispute....
The Kuril Islands dispute, known as the Northern Territories dispute in Japan, is a territorial dispute between Japan and the Russian Federation over the ownership of the four southernmost Kuril Islands. The Kuril Islands are a chain of islands that stretch between the Japanese island of Hokkaido at their southern end and the Russian Kamchatka Peninsula at their northern end. The islands separate the Sea of Okhotsk from the Pacific Ocean. The four disputed islands, like other islands in the Kuril chain that are not in dispute, were annexed by the Soviet Union following the Kuril Islands landing operation at the end of World War II
This dispute does date much further back though.
Since 2005 there's been heightened tension over who owns them...
