On May 14, 2018, 70 years later, President Donald Trump will relocate the activities of the US Embassy from Tel Aviv to Jerusalem, where it has been since 1966.
Following Trump's disputed decision last year to recognize Jerusalem as the Israeli capital, the official inauguration of the US Embassy on Monday will coincide with the 70th anniversary of the Israeli Declaration of Independence.
It will be a momentous but divisive opportunity.
What is so controversial that the US embassy is relocated to Jerusalem?
During the First Arab-Israeli Conflict 1948 Israel conquered Arab territory beyond the 1947 UN-mandated Partition Plan.
The 1949 ceasefire line, also known as the Green Line, has largely set international parameters for the borders between Israel and the Palestinians.
But the status of Jerusalem is complicated.
After the Arab-Israel War of 1967, the lines were redrawn, and Palestinian territory was called Gaza, West Bank and East Jerusalem marked.
The Palestinians recognize East Jerusalem as their capital.
Israel sees a "united Jerusalem" as its capital after it passed a law in 1980 stating that "Jerusalem, complete and united, is the capital of Israel … the seat of the President, the Knesset, the government and the Supreme Court. "https://www.knesset.gov.il/laws/special/eng/basic10_eng.htm]
So why was the US Embassy always in Tel Aviv?
The United States and most diplomatic countries Relations with Israel have always kept their messages in Tel Aviv so as not to anticipate a final decision on Jerusalem's status negotiated between Israelis and Palestinians.
The reluctance of official recognition was also perceived as a way to foster discussions between the two sides, which have largely come to a standstill since 2014, when Palestinian President Mahmoud Abbas signed an agreement to join the International Criminal Court, according to the UN Security Council a Palestinian-designed statehood had rejected a resolution calling for the withdrawal of Israeli forces from the West Bank within three years.
Although the Israeli parliament, known as the Knesset, the Supreme Court, and most other government buildings are located in Jerusalem, the Ministry of Defense and the Israel Defense Forces are in the HaKirya section of Tel Aviv.
The United States maintains a Consulate General in Jerusalem, which is responsible for relations with the Palestinians and the Palestinian Authority.
While the United States is finally planning to build a completely new embassy building in Jerusalem, on Monday the symbolic movements will send the ambassador's office and about 50 staff, including consular officials, to passport extensions in a separate, existing US facility in Jerusalem treated for Americans and visa applications for local residents.
The site spans the ceasefire lines and is partially located in no-man's-land between West and East Jerusalem.
Aside from relocating the Ambassador and his staff, the change is largely invisible, except for the installation of a new plaque on the building wall and more discreet changes and security changes.
What happens during the day?
Hundreds of guests are invited to the official opening. The embassy event starts at 4 pm. Local time, and US Ambassador to Israel David Friedman, Israeli Prime Minister Benjamin Netanyahu and Deputy US Secretary of State John J. Sullivan speak. US Treasury Secretary Steven T. Mnuchin and Jared Kushner and Ivanka Trump will also attend the ceremony.
65 journalists from the United States, 41 from the United Kingdom and more than 60 from the European Union have already arrived on their own last week to report on the incident, according to the Israeli government's press service, and others are expected before the opening.
In the meantime, Israel will celebrate 70 years as an independent state. The day after that, May 15, is the day Palestinians remember as "Nakba" or "disaster."
It commemorates the mass expulsion of Palestinians who fled or were allegedly expelled after the Israeli Declaration of Independence in 1948.
Israel claims that the Palestinians left Israel on their own or for their own safety, but some Israeli historians admit that a "handful" of expulsions have taken place. As with much of the conflict, both sides deny each other's historical events.
The sensitivity of the day and the resettlements in the US have led many people to expect an increase in protests from Palestinians angered by the recognition of Jerusalem as the capital of Israel.
The Trump administration has emphasized that resettlement does not anticipate decisions on final Israeli status, suggesting that East Jerusalem may possibly be the capital of a future Palestinian state.
But with this step seen as a blessing to the Israelis, some people are questioning the motive for the Palestinians to talk again, especially with the United States as an intermediary.
