Don't mind me, just historian humor.
For example, when explaining why Poland has taken such a strong position on the recent conflict I use the idea that Poland still hasn't forgiven the Mongols for invading them in the 13th century. Usually that gets answered with "The Mongols? Poland??? WTF!!!"
From there we can yadda-yadda through the invasions by the Turks, the Tartars, the Swedish Empire, the Turks again, Tartars again, once more the Swedes, the spillover from the 30 years war, The Russians, A partition, Napoleon, the Russians, the other partitions, the century where the Poland was literally wiped off the map, the Germans, the Soviets, the Soviets again, the Germans AND the Soviets, the Soviets for the 4th time, and then ask them "At what point would you have finally said 'ENOUGH!!!" ???"
