Why don’t you give up Hawaii and Puerto rico which you illegally annexed ? What about Mexcian lands that you stole ?

How about you don't assume my nationality, my country isn't even close those areas. Also nice whataboutism.

Baltic states were given up by Lenin to Germany in Brest treaty ,

You do realize that there were wars of independence after that treaty, that ended up with new treaties? There was the treaty of Tartu between Estonia and Soviet union, the treaty of Riga between Latvia and Soviet union and the Moscow peace treaty between Lithuania and Soviet union. The Soviet union recognized the independence of those countries so the Brest treaty is irrelevant.

they were vassals of Germany and became fascistic in later years ,

I know people like you love to throw the word around but authoritarian is not the same as fascist. And I have no idea where you take that they were vassals of German. You're clearly not aware that the independence war in Estonia and Latvia wasn't just against the Soviet union, it was also against Germany, more specifically the Baltic Germans who were in the Baltische Landeswehr.

why would Soviet Russia give up Baltic states when they got it back from Germany in 1939?

This is so far into historical revisionism there's nothing to correct, it's complete fiction.
