Evil USSR Stole Subcarpathia

So I read in the Czech periodical, Reflex how USSR took the eastern province of Subcarpahian Rus from them…

Czechs crying over the loss of Subcarpahian Rus, now that Transcarpathian region of Ukraine is actually cute. The purpose of the article is to show the USSR as bad. But sadly for any Czech claims, Subcarpathian Rus became part of Czechia by accident. The local Rusyn population could not join the West Ukrainian People’s Republic because the latter was destroyed by the newly recreated Rzeczpospolita, and the Western Allies did not want to give this territory to Hungary.

During the interwar period, Ukrainian nationalism took root among the locals and in 1939, they declared the Carpathian Ukraine. The territory was promptly occupied by Hungary, and in 1944, the Soviets annexed the territory to Soviet Ukraine. And now tell me, who has more right to the territory? Hungary because of a sizable Hungarian minority? Ukraine because the Slavic population, which. Is the majority identifies with Ukraine? The territory has never been historically part of any Czech state. Even in Habsburg or Jagelon monarchies that included the Czech lands, this was a territory of Hungary.

So did the Soviets make a mistake by incorporating this area into Ukraine? If that is so, perhaps we should right historical wrongs.
