The opening of the US embassy in Jerusalem has brought serious consequences. There has already been 59 Palestinians killed and more than 2,400 injured by the Israeli fire during protests against the US embassy re-opening. A breif summary of the relationship between these two as below (from Wikipedia).
Jerusalem
Jerusalem has been sacred to the Jews for roughly 3,000 years since King David proclaimed it his capital in the 10th century BCE. Christianity reveres Jerusalem for its Old Testament history, and also for its significance in the life of Jesus. Jerusalem is the third-holiest city in Sunni Islam. This is primarily due to Muhammad's Night of Ascension. Muslims believe Muhammad was miraculously transported one night from Mecca to the Temple Mount in Jerusalem, whereupon he ascended to Heaven to meet previous prophets of Islam.
Zionism and the British Involvement
Since the existence of the earliest Jewish diaspora, many Jews have aspired to return to the "Land of Israel". The first and second wave of modern Jewish migration was around late 19th and early 20th century mainly due to pogroms in Eastern Europe and Russia.
The circumstances started to change after the UK started to involve in the issue. The involvement was based upon geopolitical calculations. During the 19th century, the French influence had grown in Palestine and the wider Middle East as protector of the Catholic communities began to grow, just as Russian influence had grown as protector of the Eastern Orthodox in the same region. The UK was left behind, and was looking for an issue which can enhance their influence in the region. This is when they found the idea of "restoration of the Jews". After some effort being unseccessful, the UK government started to have discussion on Zionism as soon as it declared war on the Ottoman Empire (World War I). At 1917, the Balfour Declaration was made, announcing support for the establishment of a "national home for the Jewish people" in Palestine, then an Ottoman region with only 3-5% of Jewish population. After the war ended, the UK ruled the area, and the League of Nations granted the UK a mandate over Palestine in 1922. UK support and the rise of Nazism led to a dramatic increase in the number of Jews in the area, which caused the Arab revolt of 1936-1039 during which over 5,000 Arab population were killed. By the end of World War II, the Jewish population increased to 33% of the total population.
After World War II, the UK found itself in intense conflict with the Jewish community since it introduced immigration limits after the Arab revolt, as well as continued conflict with the Arab community over limit levels. After a terrorst attack by the paramilitary Zionist organisation, the UK announced it would withdraw from Palestine, stating it was unable to arrive at a solution acceptable to both Arabs and Jews.
