The United States has for the past 70 years never accepted, to move its embassy to Jerusalem, even though the US Congress, in 1995, passed a law to move the embassy, unless the President signs a waiver. No president did until Trump.
He had campaigned to do so and after he won, he made his son-in law Jared Kushner, a 36 year old, with no experience or education in foreign policy but a Zionist ( believe in the idea of Greater Israel...Eretz Israel, that the land is totally Jewish, an Orthodox Jew and major contributor to Israeli settlements on the West Bank. He was not only unqualified but clearly biased and driven by religious zeal.
Dec. 2017 and Trump has poured gasoline on the fire and the Muslim/ Arab world is joined by all other countries ( with the exception of Taiwan, Vanuatau). Netanyahu, the Israeli PM and a believer of Zionism ( very much influenced by his father, a leader in that movement), deliriously declared it " a historic day for Zionism" ( once voted in the UN as " Racism" as it excludes all non-Jews).
Trump sent his vice-president, the religious fundamentalist Pence, on a charm offensive to the Middle East but he was rebuffed by all leaders,who refused to meet him and Trump's gambit of photo ops with smiling Arab leaders, fell flat. The crown prince of US ally, Abu Dhabi said " it extended a life line to terrorists"and indeed it is as it will be used as a recruiting device in the roiling streets.
Netanyahu has launched a European selling tour and in France, his first stop he was told by Pres. Macron that it is " a danger to peace". The next stop is a meeting with the foreign ministers of the 28 in Brussels and Europe has called for a detailed plan from Trump, who of course does not have one. There is a meeting of the Security Council and Trump's mouth piece, Nikki Halley has attacked the UN as being responsible for there not being peace. She is ignorant of US/UN history or just lying for her boss.
This action by Trump breaks international law; goes against UN resolutions supported by the US and the Security Council. He is a known Muslim-hater and has repeatedly tried to ban Muslims from entering the US ( his executive orders have been struck down by the courts but he keeps making them). Even the autocratic leader of Turkey has come out with a blistering attack and there is a battle of vitriol between him and Netanyahu.
The Pope has expressed " deep concern", and British PM MAY, calls it " unhelpful" and "the British embassy is based in Tel Aviv and have no plans to move it". Marco Rubio and some Jewish lawmakers support the move but not Nancy Pelosi who calls it "premature" and warned of "mass protests".
Those protests have broken out. The streets of Palestine....West Bank, Gaza are erupting and From Pakistan to Indonesia to Morocco to Lebanon and in the Middle East and elsewhere and it will get worse. Already there has been one bomb attempt in New York
Trump has sown the winds of division and the whirlwind of violence is forming.
