Russia, before World War II, both sides also hated each other. During World War II, the Soviet Union carried out the terrible Katyn massacre in Poland, and tens of thousands of Polish civilians were collectively executed on the grounds of anti-Soviet. The logic of the Soviet Union is very funny. I sent troops to invade your country. You can't object to me. If you oppose me, I will kill you. Just like what the Japanese did in China, this incident is equivalent to the feelings of the Nanjing Massacre in the hearts of Poles. Therefore, after Poland got rid of Soviet rule at the end of the 20th century, all the traitors under Soviet rule were arrested and executed for crimes against humanity and treason. Their views on the pro-Soviet government are the same as ours on the Wang puppet government. Today, the elderly in Poland will educate their children on the day their children go to school, that is, on September 1 Sunday, saying that when I was your age, I went to school on the same day. I looked up when I was walking on the road, and the sky was full of bombs dropped by German planes. People were killed everywhere, and then our country was occupied. Poland and Germany are thicker than water, but in the face of fascist Russia, Poland resolutely chose to put aside hatred and join hands with Germany. Today, hundreds of German NATO soldiers are stationed in Poland.
