Writing in the Washington Post in 2014, Henry A. Kissinger who was US secretary of state from 1973 to 1977, noted,
“The West must understand that, to Russia, Ukraine can never be just a foreign country. Russian history began in what was called Kievan-Rus. The Russian religion spread from there. Ukraine has been part of Russia for centuries, and their histories were intertwined before then. Some of the most important battles for Russian freedom, starting with the Battle of Poltava in 1709, were fought on Ukrainian soil. The Black Sea Fleet — Russia’s means of projecting power in the Mediterranean — is based by long-term lease in Sevastopol, in Crimea. Even such famed dissidents as Aleksandr Solzhenitsyn and Joseph Brodsky insisted that Ukraine was an integral part of Russian history and, indeed, of Russia.”
He proposes four principles for geopolitical stability in the region –
“1. Ukraine should have the right to choose freely its economic and political associations, including with Europe.
2. Ukraine should not join NATO, a position I took seven years ago, when it last came up.
3. Ukraine should be free to create any government compatible with the expressed will of its people. Wise Ukrainian leaders would then opt for a policy of reconciliation between the various parts of their country. Internationally, they should pursue a posture comparable to that of Finland. That nation leaves no doubt about its fierce independence and cooperates with the West in most fields but carefully avoids institutional hostility toward Russia.
4. It is incompatible with the rules of the existing world order for Russia to annex Crimea. But it should be possible to put Crimea’s relationship to Ukraine on a less fraught basis. To that end, Russia would recognize Ukraine’s sovereignty over Crimea. Ukraine should reinforce Crimea’s autonomy in elections held in the presence of international observers. The process would include removing any ambiguities about the status of the Black Sea Fleet at Sevastopol.”
