Archduke Ferdinand's assassination and the invasion of Poland lead to two world wars.
Who started the Soviet-Polish war?

Also it would be interesting to research an ‘Intermarium’ concept and how the Polish politicians tried to pursue it in 1930s when Hitler took power.
Churchill called contemporary Poland ‘a prostitute’ and ‘a greedy hyena of Europe’. Why?
