The entire world is watching Putin play poker with the Western politicians lead by Obama and followed by Washington quislings in London, Brussels and Berlin. America's goal since the end of the Cold War has been to weaken by financial, economic and, if necessary, military means any real competition to its global financial and resource domination through the petrodollar and dollar world reserve currency status. The current trade and economic sanctions against Russia and Iran follow this time-tested action that is never successful on its own, as we know from the 50-plus-year blockade of Cuba. But this strategy can lead to opposition nations retaliating by military means, often their only alternative to end blockades etc., which are an act of war and allow the US and other democracies to bring their ultimate superior military power to bare against the offending sovereign state.
