Because Poland was occupied by Russia many times in history. In particular, the occupation of Poland during the Soviet period almost made Poland perish. Therefore, under such circumstances, the most anti-Russian country in Europe is Poland, and even willing to let opponents set foot on Polish territory to attack Russia. It is precisely because Poland pushed the debts of the former Soviet Union to Russia that Poland is the most anti-Russian country in Europe.

Poland is a big country among the small countries in Europe, and its history is very brilliant. So Poland has always been ambitious, but limited by its strength. Poland has many conflicts with its neighbors, whether with Germany, France or Russia. There have been wars and frictions in history. But Poland has always been very hostile to Russia, which is also a legacy of history. Poland requires that the border should be east of "curzon line" 150km, including almost all of Belarus and western Ukraine.

Historically, Poland and the Soviet Union fought for the border. Although the Soviet Union advanced to Warsaw, the Poles defeated the Soviet Union in China. Because the Soviet Union was eager to end the war, it did not do too much entanglement on this matter, but this matter was not perfectly solved for the Soviet Union. Therefore, this also laid a huge foreshadowing for the Soviet occupation of Poland in the later period.

Therefore, after the Soviet Union recuperated, it put forward a rectification plan for Poland's border issue. At that time, the whole of Poland was occupied by the Soviet Union, which was also a very shameful thing for Poland. Therefore, under such circumstances, Poland became the most anti-Soviet country in Europe until the disintegration of Soviet Russia and Poland became the most anti-Russian country.
