Dmitriy Trenin, director of the Carnegie Moscow Center, has been with the center since its inception. He also chairs the research council and the Foreign and Security Policy Program.
Over the weekend, one tweet that made big news around the world came from the Economist's Edward Lucas.
Above all else, it needs to stay calm. Ukraine is going through a difficult and potentially dangerous patch in its post-Soviet evolution. Up until this fall, it had managed to avoid a clear choice between Russia and the West, but the EU Association Agreement saga put that choice front and center. Whatever the end result, the choice should be Ukraine's, and it will have to live with it. Russia, as President Putin said on a number of occasions, will respect that choice and structure its relations with its neighbor accordingly.
Russia also needs to stay away from the fast-moving political developments in Ukraine. It has no reason to send its government officials and politicians there or to make public statements encouraging those it may see as its allies, as many European governments have been doing. In particular, Russia should make no move which might be seen as supporting separatist trends in Crimea or elsewhere in the Russophone south-east of Ukraine. Regional differences in Ukraine are substantial and regional attitudes to the EU and Russia vary widely, but becoming involved in a civil conflict across the border is the last thing Russia should want.
Russia should stop offering economic assistance to Ukraine. President Yanukovych desperately needs financial relief, and, in extremis, he can promise anything in return. He is fighting for his political life and, very probably, for his family's property and personal freedom, too. This does not mean, however, that he can deliver on his promises. More likely, he will later claim those had been extracted from him by threats of force. Instead, Russia should protect its economic interests vis-a-vis Ukraine, but do so in such a way as not to damage itself. In other words: the goal should be to protect oneself, rather than to punish one's partner.
Finally, Russia needs to follow the Ukrainian situation closely and be ready to adjust course at short notice. Ukraine has entered uncharted waters. Whatever the outcome of the current political standoff in Kiev and of the forthcoming presidential elections, the economic situation of the country is very difficult. This, however, is Ukraine's problem, and Russia should dearly wish that Ukraine manages it, with the European Union and the IMF providing assistance.
As for Russia itself, it needs to confound the old—and false—dictum that it can only be great if Ukraine is safely embedded within it. In the 21st century world, this is particularly not true. A hypothetical accession by Ukraine—as it presently is—to the Customs Union would only weaken Russia, drain its resources, and make the union itself unstable. The Russian Federation does not lack land, resources, or even people. The issue is upgrading the quality of governance and the quality of the people, starting with the elites. Ukraine—take it or leave it—will not help.
