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.
