Unfortunately, EU is not an entity with single and unified view on things. In the case of Russian invasion of Ukraine, there is a surprisingly strong opposition to related policies in Brussels amongst the people in quite a few member states. In fact, many support Putin and now his best buddy Trump - with plain stupid belief that Putin/Trump wants peace and Zelensky wants to continue war. In short, EU (+ UK, Norway, maybe Switzerland) is simply not as unified against Putin as it may appear in the Brussels press conferences. Putting more effort (in money, materials, soldiers even) in this conflict will be hard to pill to swallow for large percentage of citizens and by extension politicians. What I see happening in the near future is more money flowing into militaries of the member states, which is a sad necessity by having Putin as neighbor. But I'm skeptical of EU countries becoming much more involved in the Ukraine conflict.
Britain, Germany, and France alone have the military production and economy to win the war. Doesn't matter if Hungary or Ireland or whoever back out of the consortium.
These three countries have been a bit unstable politically during the last couple of years. This did not help. At least they are going in the same direction and not shooting each other’s foot.
