Those who know the history of the Middle East will tell you that the assertion that “Jordan Is Palestine” can be seen clearly in historic maps. See, after the Ottoman Empire lost control of the Middle East following World War I in 1917. As can be seen clearly in the map below, the British Mandate of Palestine consisted of a very large swath of land, incorporating what is today Gaza, the West Bank, Israel and Jordan (which was called Transjordan at the time and became Jordan in 1946). In 1923, the British split “Palestine” into two parts – Palestine, the land to the west of the Jordan River and Transjordan, the east side of the Jordan River. And the anomoly of history is that the new Palestine was merely 24% of the British Mandate of Palestine, whereas Transjordan was 76% of it. It is quite clear then, that it is much more proper to consider the land to the east of Jordan River as “Palestine” than the land to the west of the Jordan River. Yes folks – this map proves that Jordan is Palestine.
