Also true is that most if not all of the Jews who went to Palestine in answer to Zionism’s call had no biological connection to the ancient Hebrews. The incoming Zionist Jews were mainly foreign nationals of many lands, descended from those who became Jewish by conversion to Judaism centuries after the fall of the ancient Jewish kingdom of Israel and what is called the “dispersal” into “oblivion” of its people.

You need to update your knowledge on this part. At http://en.wikipedia.org/wiki/Jew#Genetic_studies you can find references to studies disproving your statement. They also indicate that the Jews and Palestinians are the same people.

These studies does support the archaeological findings and theories of Israel Finkelstein, linking the people of the region to the Canaanites.
