We can look at this question in two ways: Tymoshenko's election to the Ukrainian presidency is good for Russia because she is a businesswoman, and businessmen know how to maximize the benefits and minimize the risks. The current good relations with Russia, to avoid the deterioration of direct conflicts, is such a nationalist and pragmatic style of the "Iron Lady" will probably choose.
Ukraine, on the one hand, has a lot of workers in Russia, on the other hand, also want to use the natural gas produced by Russia, in the military industry also need to Russia's supporting production. The two countries in the humanities, economic and political, there is an indissoluble link. So given this state of affairs, Tymoshenko will not be too much of an enemy of Russia.
And on the bad side of Russia's performance: Ukraine's determination to join the European Union and turn away from Russia will certainly not change, and she will gradually push forward political reforms, fight corruption, and realize the "European value Tymmo will gradually push forward political reforms, fight corruption, realize "European values" and clear the obstacles to Ukraine's accession to the EU. Tymoshenko's attitude toward NATO is also basically clear, and she once said that only by joining NATO will she be closer to the United States, and that joining NATO is her long-held dream.
The relationship between the United States and Russia is currently very tense, at this time Ukraine will inevitably be used by the United States, borrowing her hand, provoking Russia and making unfriendly moves.
The prospect of relations between Russia and Ukraine is not optimistic, for Russia, she has no emotion, after the 2014 experience of the Square Revolution, the whole of Ukraine is trying to erase the traces of Russia, and even to erase the traces of the Russian language. Even if Tymoshenko herself is an ethnic Russian born in the Dnipropetrovsk region,she will abandon her ethnicity like most Ukrainian politicians
