Whilst I agree, I think war is the very last resort.
I think Europe should just move away from them in every way. Even if it is done slowly. And stick at it even once the orange Shitnugget dies.

The same goes with Russia. Stop importing their oil, etc. Stop people coming and going from there. However as putin already started a war with Ukraine then go all in and give Zelensky everything he needs (short of nukes) to push them back until it becomes such a drain that putin shrivels back over the border and dies. Once that happens then give them nukes again to stop it happening again.

And hopefully that will give Winnie the pooh something to think about.

Things are difficult with high prices for food and energy, etc, as it is during 'peace time' so Europe may as well just take the short term hit now.
