Frankly, the EU is only able to "think long and hard" but never to actually do anything. They have no warfighters anymore and it will take years for the member states of the EU to rebuild anything resembling military capability, if the EU even allows it. Brussels is the equivalent to the Deep State in the US but with official status, instead of being a shadow government. The only leverage EU member states have vis a vis the US is as trading partners and as vassal states for Pax Americana. If the EU wants to move away from the US, good luck. The member states of the EU are soon going to realize they are "a peninsula at the tip of Eurasia" and their best interests lie in close ties to the US.

Ukraine is in a bind, and it is sad when a buffer state is put through the meat grinder in a proxy war between two great powers. But here we are. The upside is that the Ukrainians who weren't killed in the conflict will be, along with Poland and Lithuania, the only "European" states with anything resembling a capable military. I doubt the EU members want Ukraine as a full member of NATO. Too risky. There are some proposals on the table for a more complicated peace without conceding full neutrality of Ukraine to Russia.

I don't think many people understand the nature of this conflict. They merely see "Russian aggression" but have little comprehension of great power competition and the events leading up to the hot part of this war. I feel for the Ukrainians but I wonder if any of the Ukraine boosters would shed a drop of their own blood for Ukraine. If the US demands that the Europeans take a larger role in the security of Europe, we will see if the European NATO members are up to the task. The US needs to pivot its resources to China in the coming decade. The war with Russia has been very costly and strengthened the bonds between Russia and China (and Iran and North Korea). The Europeans should take a great role in policing their own neighborhood, but I don't believe the EU, as currently constructed, is the governance vehicle capable of leading a unified Europe. The member states are, quite understandably, not happy to give up their sovereignty and culture. Participation in a common market has been a disaster for the working class of Western Europe (unless you think cheaper products is the only measure of a country's vitality). The EU experiment might be at an inflection point. They can remain in this bureaucratic quagmire, or reassert the spirit of Wesphalian sovereignty, or await the arrival of a new Charlemagne to unite a strong Europe under sovereign leadership capable of meeting the challenges of the 21st century. My money is on the decline of the EU into irrelevance and a return to the Westphalian spirit. There is no political will centered in Brussels capable of leading this ragtag assemblage of diverse states and peoples. The border problems persist. The result will be more populist revolts and ascendant "right wing" parties advocating "blood and soil" nationalism. If that's the future, then the western european states will only be supported militarily via bilateral treaties with the US or under the umbrella of a NATO dominated by the US. The latter is just the norm for the post-WWII "New World Order" so it will feel familiar. With luck, the collapse of the EU will allow EU member states to reassert control over their own borders and laws. If that happens, they should abandon this resentment of the US and be grateful they were saved from the managed decline of their central government in Brussels.
