The video is simply Palestinian propaganda based on the stupid argument that since there was a place called Palestine on old maps and coins, it proves that an independent Arab state of Palestine existed before 1948.
I debunked the argument most memorably here, where I humorously pointed out that the only people who proudly called themselves Palestinians before 1948 were Jews, and that essentially all institutions that used the word Palestine in their title were in fact run by Zionists.
More recently, I showed that a map of Palestine proudly published on the PLO NAD webpage was in fact a map of Jewish control of the land in the time of King Saul. Embarrassed, the PLO removed the map from their webpage.
In short, there is no relationship between what people call "Palestine" today and what people meant when they used the word before 1948.
Worse, the Newsweek video shows a particularly absurd version of The Map That Lies:
This has been debunked so thoroughly that textbooks and news networks that showed it apologized afterwards because they didn't want to be associated with such a blatant twisting of the truth. This version is even worse than most by calling the area that the UN proposed as "The Arab State" "Palestine" as well as the areas that were under Jordanian and Egyptian control before 1967, as obvious a falsification of history as can be imagined.
Yet Newsweek is happy to associate its name with fact-free anti-Israel propaganda.
The Newsweek and NewsweekME Twitter accounts, not to mention their email addresses, should be flooded with outraged comments on how they not only crossed but obliterated the line between journalism and pure lying propaganda.
