You're the master of superficial and senseless statements. Ukraine has already signed the trade agreement with EU which was the start point for all this mess called "Maidan revolution". And what happened? Nothing. Prosperity hasn't come to Ukraine. Ukraine did not increase its exports to Europe or USA. Why? Because of very simple reason: they don't have anything essential to sell there. What they can offer for Eurpean market? What production? Prostitutes? But Romania seized the monopoly in this ground. What else? Maybe airplanes? But Europe and USA do not buy Antonov airplanes. Engines for airplanes and helos? The same situation. What you call "the largest trading bloc on Earth" can give Ukraine nothing.
Sometimes you need to look at details, not just - oh, this is greatest trade bloc! so cool! So what? Show me your money, as Americans say.
