The move came 23 years after the passage of the Jerusalem Embassy Act of October 23, 1995, which set a deadline of May 31, 1999, for the move. The Clinton, Bush, and Obama administrations had all deferred the move. Eugene Kontorovich claimed that the decision to shift the US embassy to this area is tantamount to the United States recognizing Israeli sovereignty over land that it captured in the Six-Day War in 1967.
However, despite the move of the Embassy to Jerusalem, President Trump signed on June 4, 2018 an executive order postponing the move of the Embassy to Jerusalem, although it already moved to that city. He was required to sign the order since the Jerusalem Embassy Act requires the US Ambassador to have a permanent residence in Jerusalem, a condition not yet fulfilled.
The opening of a new US Embassy in Jerusalem led several other countries to move their embassies to Jerusalem. Two days after the US Embassy opened, Guatemala moved its embassy to Israel back to Jerusalem. Paraguay also opened a Jerusalem embassy to Israel, citing the US precedent.
^ abStephen Farrell, Maayan Lubell, U.S. Jerusalem embassy lies 'at the end of the world', Reuters, 14 May 2018: "In February, U.S. State Department spokeswoman Heather Nauert conceded that the embassy site “is located partly in West Jerusalem and what’s called the no man’s land”. This was confirmed by a senior United Nations official, who was not authorized to speak publicly given the sensitivity of the issue. “There is some uncertainty about exactly where the line runs through the property, but I don’t think there is any uncertainty about the fact that the line runs through it,” he told Reuters. “Under international law it is still occupied territory, because neither party had any right to occupy the area between the lines.” When Trump recognized Jerusalem as Israel’s capital he left the door open for Israel and the Palestinians to divide the city between them by stating he was not taking a position on “the resolution of contested borders”. But Nabil Shaath, a veteran Palestinian diplomat, said the embassy’s relocation could complicate future peace talks. “Setting the embassy on No Man’s Land is really a violation of the demographic and geographic division of Jerusalem,” he said last week."
