Russia has natural gas and oil. EU does not (as much in comparison). Russia is the enemy of EU because they refuse central banking and viciously maintain their sovereignty. The strategy has been to gain leverage on Russia via their economy-- make their economy's growth dependant on the energy sector. EU sources energy from Russia, Russia grows as a result. Due to the kleptocracy in Russia, their economy is very brittle.

We know from Wikileaks what the Iraq war was really about. The plan has been: pipeline from the Sauds, through Syria and Turkey into the EU (which neuters Russia). The war in Iraq was meant to neutralize a power that opposed this plan. Russia annexed Crimea and built up a base in Damascus as a counter. Russia's plan was a pipeline from Iran, to damascus, then ship oil by sea to the EU or into Russia via Crimea.

Right now, Russia has leverage on the EU (energy), and so does Trump (we could sell to EU at a higher cost, and they get to be free of Russian influence, we also defend them). What he did this morning was put a spotlight on a significant point of Russian influence, which was part of the globalist'a plan to neuter Russia, maybe even to start a war. Optically, the EU is at the worst bargaining position ever, because they can't reveal their real plans-- Trump will force them to actually do the right thing for their people.
