"Leftist"?

American knowledge and understanding of foreign affairs:

The boundaries of the proposed new Arab and Jewish states do not satisfy Zionist aspirations from either the political or the economic viewpoint, and the whole plan of partition with economic union is totally unacceptable to the Arabs. Although frequent reference has been made to “sacrifices” accepted in the interest of compromise, the partition plan was strongly supported by the Jewish Agency for Palestine and by various Zionist organizations favoring the establishment of a sovereign Jewish political state in Palestine. It did not, however, have the support of the Irgun, the Revisionists or the Stern gang (the so-called leftist groups), whose influence among the Jews of Palestine appears to be increasing.

That was from here in January 1948.
