So the secret clause was inevitable and necessary. The soviet union had to attack Poland together with Germany and had to do horrible atrocities while doing so? You don't take anything serious other than soviet apologism.

It was no doubt disgraceful that Soviet Russia should make any agreement with the leading Fascist state; but this reproach came ill from the statesmen who went to Munich. […] [The German–Soviet] pact contained none of the fulsome expressions of friendship which Chamberlain had put into the Anglo‐German declaration on the day after the Munich conference.

Indeed Stalin rejected any such expressions: “the Soviet Government could not suddenly present to the public German–Soviet assurances of friendship after they had been covered with buckets of filth by the [Fascist] Government for six years.” The pact was neither an alliance nor an agreement for the partition of Poland. Munich had been a true alliance for partition: the British and French dictated partition to the Czechs.

The Soviet government undertook no such action against the Poles. They merely promised to remain neutral, which is what the Poles had always asked them to do and which Western policy implied also. More than this, the agreement was in the last resort anti‐German: it limited the German advance eastwards in case of war, as Winston Churchill emphasized. […] [With the pact, the Soviets hoped to ward] off what they had most dreaded—a united capitalist attack on Soviet Russia. […] It is difficult to see what other course Soviet Russia could have followed.

When [the Fascists] attacked Poland, the Soviets moved into Latvia, Lithuania, and Estonia, the Baltic territories that had been taken from them by Germany, Britain, and Poland in 1919. They overthrew the [anticommunist] dictatorships that the Western counterrevolutionaries had installed in the Baltic states and incorporated them as three republics into the USSR. The Soviets also took back Western Byelorussia, the Western Ukraine, and other areas seized from them and incorporated into the Polish [anticommunist] dictatorship in 1921 under the Treaty of Riga.

This has been portrayed as proof that they colluded with the [Fascists] to gobble up Poland, but the Soviets reoccupied only the area that had been taken from them twenty years before. History offers few if any examples of a nation refusing the opportunity to regain territory that had been seized from it. In any case, as Taylor notes, by reclaiming their old boundaries, the Soviets drew a line on the [Fascist] advance which was more than what Great Britain and France seemed willing to do.
