Eventually Poland will have to choose between absorbing into Germany or live alongside with Russia. Do you see any alternatives?
We choose freedom. That is what NATO is for.
If Ukraine joined NATO and EU when it could - like Baltic States, Poland, Czechs, Slovaks, etc - there would be no war. Russia isn't invading Latvia or Estonia. It's invading whatever it can get away with - meaning the less smart countries that haven't managed to get into NATO in time (like Georgia and Ukraine).
Tt's not that Russia fears NATO defences of Estonia, forces deployed there are relatively weak. What Russia fears is NATO's retaliation after such an attack and NATO taking Estonia back while destroying Russian invasion force.
Since when Poland had long tradition of democracy?
Casimir IV was the king who granted the nobility a set of priviliges that later, during the reign of his children, especially Sigismund I, became the foundation of nobility democracy.
Basically 8-10% of the population co-ruled Poland by electing their representatives to the Parliament composed of two Houses.
At the same time Russian Ivans (III and IV) were murdering nobility to institute autocratic rule.
Being able to vote for a candidate of one's choosing is a freedom Russians simply do not have. Even an Africa-born president chosen by the people would be much better than a Kremlin nominated satrap.
