“Do they have a point”
If someone runs a fire safety campaign (there always is in out community, especially in Kislev), they have a point when they say “I told you so” when the house catches fire. But it doesn’t do any good to lecture on fire safety when the house is burning.
The Zionists (both the various socialist groups, and the nationalists) can be blamed for the current war (and arguably the Holocaust) based on dumb decisions made 100 years ago (and sharing credit with the British Colonial Office and the various Palestinian leaders, in that order). But the house is on fire now, and that fire is very much capable of spreading to engulf the world. And absent time travel or going to an alternative universe, there is anything we can do now to repair the mistakes of a century ago (so yes, Neturei Karta has a point, but it is moot).
