That, sir, is a lie. The Nakba (you spelled it wrong) has always referred to the permanent displacement of 750,000 Palestinian Arabs and the depopulation of entire villages by the IDF militia. The myth that the Arab states created the refugee issue did not emerge until after the war, and was one of many comforting lies Israeli's were taught to believe until it's own historians began debunking them in the late 70s and 80s.

Also, I'm familiar with Lester Golden's work. If you scroll down in the comments section, you will see me commenting on that very post. He is a clear apologist who argues that Palestinians "don't exist" and that they were never a real country, so the ethnic cleansing was somehow justified. Citing him is a perfect example of using the echo chamber to reinforce arguments (or as I like to say "the circle jerk") :P

Additionally, I can no longer access that article since I am no longer a subscribed member here. If you have a link to the actual speech, I would be happy to address it.
