If Ukraine becomes a russian satellite again... then so will Poland.
Scaremongering.
Russia has neither the intention of nor capability to conquer Poland. Also, what would be the purpose? Ukraine gives them heavy industry, the best farming lands in the world and strategic depth. What would Poland give them? Lifetime supply of holy water and constant source of problems, unrest and uprisings? Nonsensical.
Jonno is right is his cynicism, I'm afraid. Poland wants Ukrainian immigrants to stay here - they are the best kind: culturally similar, quickly assimilating, contributing around 3% of our GDP, and paying around 20 billion pln in taxes (much more than they receive in social help). If Ukraine wins and becomes the next Slavic Tiger, those people might want to go back there. If Russia conquers them, they will stay here. Also, other factors that Jon seems to imply, although it's cruel, also point to Ukraine losing the war as not being the worst scenario for Poland.
I would tend to think that after the war Ukraine and Poland might find a lot of areas to complement each other's economies and cooperate, but who knows - Jon knows Ukrainians better - maybe they would indeed try to "replace" Poland in many areas instead of peacefully cooperating with us. Fair play to Jon357 for pointing this out to us.
