depends entirely on how you see the concept of zionism. If you limit it to jews thinking they need a homeland, fine. It you think it means they need a homeland and it needs to be where a bunch of people already live now, then thats clearly a huge problem. Ben Gurion said it had to be on the site of the old kingdom, and the people there needed to be driven out. Thats ethnic cleansing and it has led to genocide and untold oppression and crimes against humanity. Its currently worse than the nazis because the rank and file israelis know exactly the severity of crimes going on in their name, which was not the case for nazi germany.
