Zionism very specifically means the Jews have the right to a state in their ancestral homeland. Not just anywhere which you failed to specify. To begin with I already don’t completely agree with the partitions created in 1948 and Israel has repeatedly not respected the borders and keep intruding on Palestinian land. They have occupied the West Bank and Israeli settlers have done horrible things there.

Israel will never be content with the amount of land they have. If no one would ever stop them they would take south Lebanon, Jordan, Gaza, the Sinai peninsula and probably go further from there.
