It would be difficult to overstate the extremity of Mr. Trump’s departure from recent presidential practice. His immediate predecessors prided themselves on orderly, fastidious deliberations: George W. Bush as the first president with a business degree, Mr. Obama as a candidate branded by aides as “no drama Obama.”

Even Republicans concede that it is not clear how Mr. Trump’s roller-coaster approach to the transition will carry over to governing. Mr. Gingrich predicted during the Republican primary contests that a Trump administration would function as a kind of daily adventure. “If Trump does end up winning, you will have no idea each morning what’s going to happen,” he said in a January interview, “because he will have no idea.”

A more recent US State Department-sponsored report notes that "Ukraine's strategic location between the main energy producers (Russia and the Caspian Sea area) and consumers in the Eurasian region, its large transit network, and its available underground gas storage capacities", make the country "a potentially crucial player in European energy transit" - a position that will "grow as Western European demands for Russian and Caspian gas and oil continue to increase."

Ukraine's overwhelming dependence on Russian energy imports, however, has had "negative implications for US strategy in the region," in particular the strategy of:

"... supporting multiple pipeline routes on the East–West axis as a way of helping promote a more pluralistic system in the region as an alternative to continued Russian hegemony."

Here is the thing about the whole "drain the swamp" promise and other promises like that:  They are born out of a need to vilify those in power with whom you have policy differences (or, in some cases, to vilify those who are contending for the office or power you are seeking, even when there might not be significant policy differences). It is not enough to attack an opponent's policies.  So, you have the recurring theme (from this year's campaign especially) of being someone who is not part of the "establishment." Someone who will "fix" what is wrong in Washington, D.C., and stand up to the Washington, D.C. "cartel."  Some billionaires are not part of the establishment. Some incumbent Senators are not part of the establishment.  Some members of the media are part of the establishment, but others are not  Trump is not alone in making these types of claims, but he did up the ante on using vilification as a campaign strategy.  Candidates for all kinds of offices are no longer just not the best choice, they actually are evil devils who need to be locked up. This is all smoke and mirrors. Us against Them stuff.  And it works.
