Tell me why Russia and Ukraine are special countries.

1. Ukraine is completely restricted by Russia. It wants to rely on it and get rid of its bondage. Due to the fierce dispute in Crimea, both countries are members of the former Soviet Union. On the issue of the Black Sea Fleet, neither side is willing to give up control of the Black Sea. On the issue of nuclear weapons, many nuclear weapons left by the Soviet Union were left in Ukraine. Russia wants to fully inherit the nuclear weapons of the Soviet Union and is also dissatisfied with Ukraine.
