Americans in fact barred EU from Iraqi pie and in Ukraine they get the biggest share of the pie again.
Our American allies don't bother to get the biggest and most lucrative pieces of the Ukrainian pie now. They have distributed the roles in Ukraine in most weird way I should say. The EU is trusted with heavy financial burden donating huge sums for Euromaidan in Kiev and helping out Kiev with its enormous gas debts to Moscow and other financial matters.
And with Americans it was clear in spring already when son of the USA vice-president Biden joined the Executive Board of the Ukrainian gas major Burisma Holding. Nobody of EU leaders voiced any concern then or raise any alarm..... They just swallowed it!
And now Ukrainian parliament have approved the law making USA master of the Ukrainian transport system for EU destined Russian gas!! And shale gas of Ukraine will be sold to EU countries by Americans too, believe you me!
