Why? It's 100% accurate. It's not a new phenomenon either, people DEEPLY familiar with the nazis were doing it immediately after ww2. Albert Einstein (a somewhat famous jew that fled germany you may have heard of him) did that in 1948 in a letter to the New York Times when it was clear that the emerging ruling party (which has ruled Israel ever since) was fascist.

Among the most disturbing political phenomena of our times is the emergence in the newly created state of Israel of the "Freedom Party" (Tnuat Haherut), a political party closely akin in its organization, methods, political philosophy and social appeal to the Nazi and Fascist parties. It was formed out of the membership and following of the former Irgun Zvai Leumi, a terrorist, right-wing, chauvinist organization in Palestine.

It is inconceivable that those who oppose fascism throughout the world, if correctly informed as to Mr. Begin's political record and perspectives, could add their names and support to the movement he represents.

Before irreparable damage is done by way of financial contributions, public manifestations in Begin's behalf, and the creation in Palestine of the impression that a large segment of America supports Fascist elements in Israel, the American public must be informed as to the record and objectives of Mr. Begin and his movement.

until recently they openly preached the doctrine of the Fascist state. It is in its actions that the terrorist party betrays its real character; from its past actions we can judge what it may be expected to do in the future.

Within the Jewish community they have preached an admixture of ultranationalism, religious mysticism, and racial superiority. Like other Fascist parties they have been used to break strikes, and have themselves pressed for the destruction of free trade unions. In their stead they have proposed corporate unions on the Italian Fascist model.
