How did Germany and Poland cooperate to carve up Czechoslovakia during World War II?

This question is about Poland's relations with the Soviet Union and Germany at that time. The partition of Czechoslovakia was a war without smoke. Poland had certain territorial claims in Czechoslovakia since ancient times. Looking back at the early days of the German lightning invasion of Poland from 1936 to 1939, the only country Poland could bully was Czechoslovakia. In fact, the key to dividing Czechoslovakia between Poland and Germany was to fight for the skin with tigers. At that time, Germany just wanted to give Poland a little benefit to stand in the team, but Poland not only didn't stand on Germany's side, but also wanted to play the trick of neutral group between Germany and Russia, which meant that it was necessary to let Poland participate if it was beneficial to neither the Soviet Union nor Germany, which gradually made the Soviet Union and Germany feel sick, because Poland, as a not very developed country, wanted to seek the status of a big country between Germany and the Soviet Union and take sides with Britain and France in an attempt to contain Germany and the Soviet Union.

This is a typical turn of the arm, which is not very clever or pragmatic. In the end, the Soviet Union and Germany stood together and prepared to win Poland, because Poland was a stumbling block for the Soviet Union and Germany to compete for hegemony in the world at that time. Politically, Poland had no strategic consideration of political stance, and it became a local strongman, and its tail was even connected to France and Britain. Finally, in 1939, Germany decided to win Poland by blitzkrieg, and Poland was ready to invade Germany.

Czechoslovakia, which was previously carved up with Germany, became a springboard for Germany to attack Poland in an all-round way. In the end, the self-righteousness of Polish politicians led to Poland being carved up by the Soviet Union and Germany. As the allies of Poland at that time, Britain and France finally sold Poland as accommodating, in exchange for a temporary peace with Germany. Therefore, Poland itself cannot be said to be unjust, but Poland's political strategy was too stupid, and it could have been used as a chessboard in the end. The demise of Poland also made Hitler's ambition expand to the extreme in an instant. It was a matter of time before Germany won France, because Hitler had already found out the bottom line between Britain and France.
