"50 Nations voted against it this year"
If you support with money and weapons a country which renamed dozens of streets to glorify Nazi collaborators, why would you vote for the resolution condemning rehabilitation of Nazism?
There are almost 20 streets named after Bandera, the leader of OUN-B, in the Ukraine [0], including a big one in the center of the Ukraine's capital. Ukraine's ambassador to Germany compared him to Robin Hood [1].
Here is what two countries that now support Ukraine used to say before the war[2][3].
"Last week, Israel’s ambassador to Ukraine, Joel Lion, and his Polish counterpart Bartosz Cichocki wrote officials an open letter condemning the government-sponsored honoring of Stepan Bandera and Andryi Melnyk, two collaborators with the Third Reich.
The two have written on the subject before. In 2018, Lion wrote that he was shocked at an earlier act of veneration for Bandera, saying: “I cannot understand how the glorification of those directly involved in horrible anti-Semitic crimes helps fight anti-Semitism and xenophobia.”
...
Ukraine’s ambassador to Israel has told Jerusalem to butt out of the debate about honoring of Nazi collaborators."
"Israel and Poland, which have clashed repeatedly in recent years over differing interpretations of the history of the Second World War, came together on Thursday to issue a rare joint condemnation of Ukraine over its efforts to rehabilitate nationalists who collaborated with the Nazis.
The criticism came one day after Ukrainians marked the 111th birthday of Stepan Bandera, the wartime leader of the Organization of Ukrainian Nationalists (OUN), a violently anti-Semitic organization that collaborated with the Nazis. Among Holocaust historians, the consensus is that the OUN and its military offshoot, known as the UPA, were responsible for the deaths of thousands of Jews and up to 100,000 Poles during the war (estimates vary)."
