1) both based on supposed purity of blood.
2) both based on supposedly reuniting some religioethnic diaspora under one expansive state.
3) both attempting to revive some supposedly "glorious ancient kingdom" -- a "glorious ancient Teutonic kingdom" for the NAZIs; a "glorious ancient Judaic kingdom" for the Nationalist Zionists.
4) both established a state that was culturally, legally, economically and religiously based to exclusively benefit one ethnic/racial group.
5) both based on violent racist exclusion and a highly intricate complex of racial exclusion laws (like Israel's racial 'Nuremberg laws').
6) both based on creating a founding mythology -- like, for Zionist Jews, "a land without a people"
7) both invented their own race: Aryans, by the NAZIs; Jews, constructed as a unique/genetic race, by the Nationalist Zionists.
8) both based on eliminating some other unwanted and supposedly inferior races -- ethnic cleansing -- and, in the case of Zionism, removing those unwanted people who supposedly didn't exist.
9) both engaged in collective punishment and widespread torture (even inventing new sadistic torture methods),
10) both engaged in the mass imprisonment -- without trials -- of unwanted populations/races.
11) both enclosed unwanted races in walled-in ghettos and concentration camps -- only the Nationalist Zionists made the walls many times higher and the concentration camps many times larger (like Gaza, in effect the world's largest open-air prison/concentration camp).
12) both tried out new weapons on civilian populations (and Israel has engaged in the internationally illegal use of anti-personal weapons of mass destruction, like the widespread use of cluster bombs, on civilian populations).
13) both sought to erase existing countries -- like the Nazis wanting to wipe Poland off the map and parts of other countries; the Nationialist Zionists wanting to wipe Palestine off the map and parts of other countries.
14) both used pseudo-archeology to claim that it had exclusive right to the land.
15) the Nazis obsessed about "too many Jews" in Germany; Nationalist Zionists/Israel obsesses about "too many Palestinians" and the re-emergence of a Palestinian majority in historic Palestine (once an overhwhelmingly Arab land).
16) both were violently and militarily expansionist.
17) both engaged in blitzkrieg fighter aircraft and tank warfare against civilian populations and civilian targets.
18) Nationalist Zionist Israeli Jews even studied the original NAZI methods for urban warfare and clearing Palestinians out of their ghettos. Exclaimed one Israeli commander, "Let's be Judeo-Nazis!" (Reference:
www.seruv.org.il -- the website for Israeli Refuseniks in the "Occupied Territories"; see "Letter to American Jews"; "The Nazification of Israel" -- both online.)
19) both claimed to be based on "God's will".
20) and, finally (for Israel's 'final solution'), most recently (Feb 29, 2008), Israeli deputy defence minister threatens a "Holocaust" for the Palestinians.
