The European Union is seeking a way to bring Ukraine into the European Union as a non-voting member in order to continue Europe’s eastward economic expansion even as President Trump is seeking to wind down the war in Ukraine. As was understood in the 1990s increasing the size and power of N.A.T.O. would become a threat to RUssia and the United States too as Europe in the absence of the Soviet Union worked at cross- purposes to peace.
Europe does not have a history of peace- quite the opposite. Those living in generations after the Second World War have recently forgotten the lesson that a peaceful Europe was only a response to it's massive destruction eighty years ago. Europe had little choice besides being peaceful as the Soviet Union/Russia and the U.S.A. were victors with massive nuclear weapons stockpiles. Removing the eastward threat and putting N.A.T.O. on steroids elicited a return of the European proclivity for power through force.
The EU quest for power and wealth through war and economic leverage was bound to become in conflict with the United States eventually. When European interests of expansion and escalating to the mythical state of global thermonuclear war run into conflict with American and Russian interests, conflict ensues. Creating a monster size European centered N.A.T.O. was simply organizing a large scale potential future adversary for the United States. It was not good or intelligent policy.
Europe still relies on the United States for nuclear weapons and some defenses against very unlikely military threats from Russia and China. It is very improbable that in a normal circumstance of positive economic and political relations without the Ukraine conflict that Russia or China would think of moving toward an adversarial military posture with Europe. Taiwan is a potential conflict area yet the scale of economic damage to China in that event might be as great as the scale of damage in Ukraine, so China would probably opt for peaceable cooperation with Taiwan and the West as a practical affair. Attacking Europe in the event of an attack on Taiwan is also less than a rational choice for Chinese leadership to make.
Europe though is leveraging the N.A.T.O. relationship to the maximum extent to drift mine its way eastward. The EU and European N.A.T.O. members generally are fanatics about eastward expansion into the former Russian Ukraine and using the power of the UNited States to guarantee the war. Because that war is not in U.S. interests, nor in the interests of global peace and economic progress, in addition to undermining global food, environmental and nuclear security, the EU is like H.I.V. attacking the United States security and economic status globally. Building up that monster E.U. and N.A.T.O nearly inevitably assured that European and American interests eventually would be at loggerheads.
