Funny that, because something like the attack on the Exodus occured before that, and similar attacks occured in India against British forces, but we do not hear the British call India Hindu occupied Pakistan.
The Irgun and Stern gangs started around 1944, although they had undertaken smaller missions earlier, the Exodus controversy was 1946.
Stern was such a fanatic he actually met with Nazi representatives in 1941 to come to deal thereby his group was attack the British (then fighting Rommel) in return for safe passage for Jews out of Europe and a free Jewish homeland if the Nazis won the war.
