I suppose this is karma for me getting too excited about European unity getting a massive boost as a silver lining to the state of the world. My own country is joining Hungary in attempting to sabotage it.
This is not the time to make an ideological show to your populist national electorate. If this doesn't get implemented properly and the newfound unity is not credible, the continent and the EU will be faced with war. Which, if that on its own is not convincing enough, also tends to be somewhat suboptimal for fiscal stability and the economy.
One caused by counting on internal division in the EU, the probability of which increases when we fail to have a unified response right now. Basically just gambling that countries like the Netherlands won't be willing to defend, e.g., a Baltic country. Russia could certainly beat the militaries of small Baltic states one by one, if it is breaking even with Ukraine. No joint response would mean selling out member states and effectively disabling the whole concept of the EU. Joint response would mean war for everyone.
I would prefer a future that minimises the probability of this gamble being made, and nobody gets invaded.
