To those who skipped history lessons, I recall the words of Otto von Bismarck:

“Do not expect that once you take advantage of Russia’s weakness, you will receive dividends forever. Russians always come for their money. And when they come, do not rely on the Jesuit agreements you have signed, supposedly justifying you. They are not worth the paper they are written on. Therefore, it is worth either playing fair with the Russians, or not playing at all.“
