When Chomsky was a Zionist Youth Leader

From a recent exchange:-

Do you believe Israel should exist, why and in what form?
NICK HARRIS


As a Zionist youth leader in the 1940s, I was among those who called for a binational state in Mandatory Palestine. When a Jewish state was declared, I felt that it should have the rights of other states - no more, no less.

Why should the US exist, sitting on half of Mexico, including Florida, conquered in a violent racist war carried out in violation of the Constitution?

And we can ask much the same about other states. State formation has been a brutal project, with many hideous consequences. But the results exist, and their pernicious aspects should be overcome.

Anybody know what movement?
