Under the UN Would California Go Back To Mexico?

After the Portola expedition of 1769–70, the Spanish built 21 California Missions starting with San Diego. The Spanish military built forts and three settlements Los Angeles, San Diego and San Jose. The was a genocide of over 70 indigenous tribes (13,000 people) in California. Alta California was named New Spain. It became part of Mexico in 1821 after its war for independence. In 1848 was ceded to the United States before becoming a state in 1859. So in 1848, if there was a United Nations. The resolution in front of a security council would be. 
"Guided by the purposes and principles of the Charter of the United Nations, and reaffirming, inter alia, the inadmissibility of the acquisition of territory by force.
Reaffirming the obligation of the United States, the occupying Power, to abide scrupulously by its legal obligations and responsibilities under the Fourth Geneva Convention relative to the Protection of Civilian Persons in Time of War, of 12 August 1949, and recalling the advisory opinion rendered on 9 July 2004 by the International Court of Justice, Condemning all measures aimed at altering the demographic composition, character and status of the Native American land occupied since 1848, including Los Angeles, including, inter alia, the construction, and expansion of settlements, transfer of American settlers, confiscation of land, demolition of homes and displacement of Mexican civilians, in violation of international humanitarian law and relevant resolutions."
So the United States should give California back to Mexico?
So why should Israel back down?
The White House was behind the resolution by definition because anyone working on the resolution would want to know if America is going to veto it or not in would try to get America to agree to the wording.  Also by definition, the people have the right to know, but when you have 14 other members of the UN Security Council were all talking to each other, you have collusion. John Kerry meeting with New Zealand Foreign Minister the last month and they were talking about this resolution.
In the in the Wall Street Journal this morning Bret Stevens writes "The administration was deceptive about the motives for the 2012 Benghazi attack. It was deceptive about Sgt. Bowe Bergdahl’s service record, and the considerations that led it to exchange five Taliban leaders for his freedom. It was deceptive about when it began nuclear negotiations with Iran. It was deceptive about the terms of the deal. It continues to be deceptive about the fundamental aim of the agreement, which has less to do with curbing Iran’s nuclear ambitions than with aligning Washington’s interests with Tehran’s.
Now the administration is likely being deceptive about last week’s U.N. vote, claiming it did not promote, craft or orchestrate a resolution that treats the Jewish Quarter of Jerusalem’s Old City as a settlement in illegally occupied territory. Yet in November, John Kerry had a long talk on the subject with the foreign minister of New Zealand, one of the resolution’s sponsors."
"
Minister of New Zealand along with the eminent cosponsors Venezuela Malaysia and Senegal to embarrass and endanger the United States Democratic ally. The world Jewish Congress is calling for hearings investigation. Obama has a personal responsibility protect our country and protects our national interest this resolution goes against American national interest that's the big scandal residue that, This resolution that affects Israeli settlements go against American national interest. They should have supported Western civilization from the three major worldwide terror organizations around Al Qaeda, Isis, and the Muslim brotherhood. Israel's doing everybody a big favor by defending them from these organizations. Israel also defends Christians Jews and Muslims in Judea and Samaria.  It also protects Palestinian Arabs. Jews living in Judea and Samaria for 3800 years ever since Abraham. Americans have only been on it's territory for 400 years in New Zealand hundred and 75 years.
 
Talking to most Muslims and Druze living in Israel the like the current situation because the Israel Defense forces protect them every day from the three worldwide terror organizations. The number one victim of the three terror organizations are Muslims, and the Jews are Israel is defending Muslims and Christians. If we apply the logic of the UN then California needs to go back to Mexico.
