For those of you who are still unsure why Israel really isn't a product of 20th century European colonialism, you must read this.

The short version:

Jews came to a land where they had a history and a population, they were not seeking to settle "unexplored" territory

Jews came not to acquire, but to escape genocide or second-class citizenship

Most Jews in Israel are descended from immigrants from the East not the West

Most colonial powers never agreed to various partition plans with the "native population"

The argument is not that Palestinians haven't suffered, just that to lump Zionism with traditional colonialism is way off the mark.
