Before World War 2?
What a wonderful product of our public education system. Someone who believes the Ottoman Empire fell during World War 2.
After the Ottoman Empire fell in World War 1, the League of Nations carved up the Ottoman Empire's territory and gave the Arab Muslims much of the Middle East.. including Arabia, Iraq, Syria, etc. They also gave the Jews back their homeland, but refused to name it back to Israel. So the Jews had the land that stretches from the farthest Western point of Gaza to the most southern border of Lebanon, to the most Eastern border of Jordan. The Arab Muslims complained so they split Palestine in two and created Trans-Jordan, which covers all of the land that Jordan is today and Palestine. Still the Arabs complained and the United Nations gave them half of the land that Israel has right now and called that Palestine and the other part they called Israel. The Arabs, unhappy with the Jews having any part of land that wasn't theirs to begin with, declared war on Israel and lost all of their land that was known as Palestine. Then, in 1967, Israel captured Jerusalem, the West Bank, Gaza and the Golan Heights. In 1973, Israel captured all of the Sinai Peninsula.
The only claim the Arab Muslims have to Israel is that they won it through a war with the Persian Empire nearly 1000 years ago. If that's the logic they use, that it's ok to have land once you conquer it via war, then Israel should rightly belong to the Jews because it's the Jews who conquered the Arabs in 1948, 1967 and 1973 and we will do so again and again and again, God willing until either the Arabs are finally destroyed or they come to their senses and make peace with Israel.
