アラスカ購入
At the beginning of the 21st century, a resurgence of Russian ultra nationalism has spurred regret and recrimination over the sale of Alaska to the United States. There are periodic mass media stories in the Russian Federation that Alaska was not sold to the United States in the 1867 Alaska Purchase, but only leased for 99 years (= to 1966), or 150 years (= to 2017)—and will be returned to Russia. However, the Alaska Purchase Treaty is absolutely clear that the agreement was for a complete Russian cession of the territory.
