Putin did.
Historians say the litany of claims made by the Russian president are nothing more than a selective abuse of history to justify the ongoing war in Ukraine.

Russians are living in an alternate self-made history, which is something to take into consideration to understand their current point of view.
Now, I will need to study more of your alternate history, I suppose it could explain a few things.
Here are some passages from two chapters of Churchill's memoirs to start your research.
He regarded the Polish action in seizing their chunk of Sudetenland as "shameful" and that they were like German "vultures" on Czechoslovakia's carcass; and "grovelling in villainy".
France's leaders were even more vicious in their opinions of Polish actions in 1938. Best you find and read them in the original French if you're really interested.

Chapter 18
Munich Winter
On September 30, Czechoslovakia bowed to the decisions of Munich. “They wished,” they said, “to register their
protest before the world against a decision in which they had no part.” President Benes resigned because
“he might now prove a hindrance to the developments to which our new State must adapt itself.” He departed
from Czechoslovakia and found shelter in England. The dismemberment of the Czechoslovak State proceeded in
accordance with the Agreement. But the Germans were not the only vultures upon the carcass. Immediately after
the Munich Agreement on September 30, the Polish Government sent a twenty-four-hour ultimatum to the Czechs
demanding the immediate handing-over of the frontier district of Teschen. There was no means of resisting this
harsh demand.
The heroic characteristics of the Polish race must not blind us to their record of folly and ingratitude
which over centuries has led them through measureless suffering. We see them, in 1919, a people restored by the
victory of the Western Allies after long generations of partition and servitude to be an independent Republic
and one of the main Powers in Europe. Now, in 1938, over a question so minor as Teschen, they sundered
themselves from all those friends in France, Britain, and the United States who had lifted them once again to
a national, coherent life, and whom they were soon to need so sorely. We see them hurrying, while the might
of Germany glowered up against them, to grasp their share of the pillage and ruin of Czechoslovakia.
During the crisis the door was shut in the face of the British and French Ambassadors, who were denied even
access to the Foreign Secretary of the Polish State. It is a mystery and tragedy of European history that a
people capable of every heroic virtue, gifted, valiant, charming, as individuals, should repeatedly show such
inveterate faults in almost every aspect of their governmental life. Glorious in revolt and ruin; squalid and
shameful in triumph. The bravest of the brave, too often led by the vilest of the vile! And yet there were
always two Polands; one struggling to proclaim the truth and the other grovelling in villainy.

Prague, Albania, and the Polish Guarantee
January-April, 1939
The Slovaks formally declared their independence. Hungarian troops, backed surreptitiously by Poland,
crossed into the eastern province of Czechoslovakia, or the Carpatho-Ukraine, which they demanded.
Hitler, having arrived in Prague, proclaimed a German Protectorate over Czechoslovakia, which was thereby
incorporated in the Reich.
...
The Poles had gained Teschen by their shameful attitude towards the liquidation of the Czechoslovak State.
They were soon to pay their own forfeits. On March 21, when Ribbentrop saw M. Lipski, the Polish Ambassador in
Berlin, he adopted a sharper tone than in previous discussions. The occupation of Bohemia and the creation of
satellite Slovakia brought the German Army to the southern frontiers of Poland. Lipski told Ribbentrop that the
Polish man-in-the-street could not understand why the Reich had assumed the protection of Slovakia, that
protection being directed against Poland. He also inquired about the recent conversations between Ribbentrop
and the Lithuanian Foreign Minister. Did they affect Memel? He received his answer two days later (March 23).
German troops occupied Memel.
