The monotonously endless anti-Russia crusade serves a number of political agendas for Democrats and the Washington power structure.  It rationalizes Hillary Clinton’s stunning defeat, delegitimizes and weakens the Trump presidency, sets momentum for impeachment, and helps drive up Pentagon (and intelligence) spending.  Often forgotten is a yet another, deeper factor: Russia has long been targeted as an intolerable obstacle to U.S. Eurasian supremacy, years before the Trump phenomenon was on the horizon.
