Also, being Jewish doesn't necessarily mean you support the behaviour of the Israeli state, as evidenced by the picture above.
Neturei Karta describe this well:
This Torah contains the basic doctrines of our faith, Divine commandments and the narrative of the earliest Jewish and general human encounter with G-d.
Throughout the centuries Jews pledged their assent to this Torah even when their lives were at stake. They maintained this loyalty with almost unanimous allegiance until the dawn of the modern age. In the three hundred - odd years since the so - called Enlightenment began, Jews and Gentiles throughout European civilization have been losing many souls to its evil clutches.
Today unfortunately there are many Jews who, through no fault of their own, are ignorant of, and fail to, practice the basics of their faith. This is a great tragedy for many reasons. Perhaps paramount among them is the falsification of Judaism that results when those unaware of its basic assumptions speak to the general public.
It behooves all Jews loyal to their faith to proclaim to the world the truths of Judaism in as lucid a manner as possible.
Neturei Karta International is dedicated to the propagation and clarification of Torah Judaism.
Its only loyalty is to G-d and His revelation.
One of the basics of Judaism is that we are a people in exile due to Divine decree.
Accordingly, we are opposed to the ideology of Zionism, a recent innovation, which seeks to force the end of exile. Our banishment from the Holy Land will end miraculously at a time when all mankind will unite in the brotherly service of the Creator.
In addition to condemning the central heresy of Zionism, we also reject its policy of aggression against all peoples. Today this cruelty manifests itself primarily in the brutal treatment of the Palestinian people. We proclaim that this inhuman policy is in violation of the Torah.
NKI seeks peace and reconciliation with all peoples and nations. This is especially needed in our relations towards the Islamic world where Zionism has for 53 years done so much to ruin Jewish - Muslim understanding.
