On 24 April 1950, when the Hashemite regime unlawfully and illegally annexed Judea and Samaria, it violated the 4th Geneva Convention (which prohibits forcible transfer of populations) by transferring a segment of it’s Arab population into these liberated territories.
International Humanitarian Law
International Humanitarian Law (IHL) or the Laws of Armed Conflict (LOAC) prohibits the transfer of segments of the population of a state to the territory of another state which it has occupied as a result of the resort to armed force. This principle, which is reflected in Article 49(6) of the Fourth Geneva Convention (1949), was drafted immediately following the Second World War and as a response to specific events that occurred during that war.
As the International Red Cross’ authoritative commentary to the Convention confirms, the principle was intended to protect the local population from displacement, including endangering its separate existence as a race, as occurred with respect to the forced population transfers in Czechoslovakia, Poland and Hungary before and during the war. Quite apart from the question of whether the Fourth Geneva Convention applies de jure to territory such as Judea and Samaria …, the case of Jews voluntarily establishing homes and communities in their ancient homeland, and alongside Palestinian communities, simply does not match the kind of forced population transfers contemplated by Article 49(6).
The fact is that the Hashemite regime ethnically cleansed Jews from Judea and Samaria, and from East Jerusalem in violation of Article 49(6) of the Fourth Geneva Convention (1949).
