To say the us gave the Jews Israel is a gross oversimplification.
First off, know that Israel is the historic, ancestral, cultural, and religious homeland of the Jewish people. The Israelites, likely a sub tribe of Canaanites, who are the predecessors of modern Jews, originated in the land of Israel and 2500+ years ago had sovreignty over the land- the had the kingdom of Israel which later split into the kingdom of Israel and kingdom of Judah (the word Jew derives from the hebrew word "y'hudi" meaning "from Judah."
So Jews have lived in Israel continuously since ancient times, but migrations and two major exiles (the Babylonian exile in 586 CE and the roman exile in 70 CE) dispersed Jews around the globe, with most exiled Jews going to Europe, North Africa, and the Middle East.
So Jews eventually became a small minority in their own land, which came to be ruled by the Assyrians, Babylonians, Persians, Greeks, Jews again (hence the story of Hanukkah), Romans, Byzantines, Arabs, European Crusaders, Mamluks, Ottoman Turks, the British, and then the Jews again (state of Israel).
The Arab invasion of Israel in the 7th century forced many Jews to adopt Arabic culture and Islam, and thus many Palestinians have mixed Jewish and Arab ancestry. Arabs- who really were of mixed Canaanite/Jewish and Arab ancestry- became the majority while Palestinian Christians, Druze, and Jews were all minorities for hundreds of years.
The Arabs ruled Israel for a very long time, but not as an indpedent Palestinian country. Rather, Israel was part of the Arab Muslim caliphate which encompassed all of the Middle East and beyond.
Then the ottoman Turks took the land over and ruled it for hundreds of years, than after WWI the British took over, and in 1948 most of the land went to the Jews (although Arabs were supposed to get half), and Jews from all over the world (mainly Europe and Arab countries) returned to Israel after thousands of years in exile.
So the Jews did own Israel at one point, but thousands of years ago. It was always their native land. But not always the country they ruled. Most of the time, as previously stated, Jews were a minority.
