Why does Zelenskyy invoke tragic events?

Since Russia invaded Ukraine in February, Ukrainian President Volodymyr Zelenskyy has invoked the Holocaust to Israel, the Blitz to the British Parliament, Pearl Harbour to the U.S Congress, and the Berlin Wall to the German Bundestag. The most inappropriate comparison has definitely been the Holocaust, because this was not a war or an attack on a nation for political reasons. Jewish people were systematically targeted by the Nazis and there was absolutely no provocation for it, and nothing they could do about it. As I have said to people in my post about Ukraine, in a war you are presented with choices...you can choose to fight, or you can choose to surrender. If you surrender, the general rule is that your army and your people will no longer be under attack. Even if they have to live under an oppressive government, they are still *not* going to be subjected to mass murder in the way that Jewish people were during the Holocaust.

It seems to me that Zelenskyy will just use whatever tragic event he can with the intention of targeting his specific audience with it. This is obviously because he wants to get something out of them (e.g military equipment, financial aid, etc.) but it's so incredibly disingenuous. I think his thoughts on the Holocaust in particular are testament to how so many former Soviet (yes, I know it doesn't exist now but the mentality still does) Jews still view the Holocaust. I know that many in Ukraine and in other former Soviet States do recognize the horror for what it was...there are some who just don't though. I see Zelenskyy as more of a Ukrainian nationalist than as someone whose great-grandparents perished because they were Jews. His grandfather and other family members were allowed by the Soviets to join the Soviet Army.

In Ukraine, because of a combination of Soviet policies and Ukrainian nationalism, there historically hasn't been that much openness about the Holocaust and how Jewish people were slaughtered en masse simply for being Jews. They were told that all people in Eastern Europe suffered, and that the Nazis killed everyone. They were made to believe, or at least say they believed, that there was nothing unique to Jewish suffering. I think if Zelenskyy had a greater awareness and didn't prioritize nationalism over basic historical realities, he could never have used the Holocaust as a comparison to what is presently happening in Ukraine. It's genuinely beyond comprehension that he did.

Back to the wider point I am making though, it isn't right or fair to go to other nations and bring up unfortunate events they have had in recent history just to get your own way.
