British Empire and a group of violent Ukrainian and Polish fanatics on top of the land of others.
Also Serbian and Hungarian. Theodor Herzl was the founder of zionism, and ironically he was an atheist, which points out how a big chunk of zionisms's ties to judaism is just LARP and cooptation, specially to justify atrocities commited in Mandatory Palestine and the ethnic cleansing post 1947 and their alleged claim to the land.
I'd say there are different types of nationalism and nationalists, some do represent valid historical gripes, context and claims particularly in the third world. Then you have stupid nationalism, like the nazis, where the ideas are so incoherent, contradictory with the claims and the historicty where you end in some form of racial/religious supremacy because you have nothing else to back it up, which causes all sorts of idiotic and irrational choices, leading to the demise of the nationalist project.
Zionism falls into the stupid nationalism type. They have only lasted this long by a number of unique factors, namely the West's need for a bulwark against the USSR in the region during the Cold War and them providing it and later on Iran. The whole religious nutjob aspect of it is far more recent and probably tied to the fall of the USSR as rallying point of interests, so you gotta come up with something else.
Which ends up being something stupid, as stupid nationalism does, leading to increasingly irrational decisions.
The conditions that allowed all of this are changing, though, specially as the US hegemony and influence weakens, plus the inability to control the narratives due to social networks and the loss of trust in traditional news outlets.
