Just an obvious point: the UN building is on extraterritorial land, like any embassy.
To Walt: The U.N. is an organization not a government.
In any event pass H.R. 204 and the problem is solved:

Sec 6
(b) Diplomatic immunity.—No officer or employee of the United Nations (including any organ, specialized agency, commission or other formally affiliated body of the United Nations) or any representative, officer, or employee of any mission to the United Nations of any foreign government shall be entitled to enjoy the privileges and immunities of the Vienna Convention on Diplomatic Relations of April 18, 1961, nor may any such privileges and immunities be extended to any such individual. The privileges, exemptions, and immunities provided for in the International Organizations Immunities Act of December 29, 1945 (59 Stat. 669; 22 U.S.C. 288 et seq.), or in any agreement or treaty to which the United States is a party, including the agreement entitled “Agreement Between the United Nations and the United States of America Regarding the Headquarters of the United Nations”, signed June 26, 1947 (22 U.S.C. 287 note), and the Convention on Privileges and Immunities of the United Nations, entered into force with respect to the United States on April 29, 1970 (21 UST 1418; TIAS 6900; UNTS 16), shall not apply to the United Nations or to any organ, specialized agency, commission or other formally affiliated body of the United Nations, to the officers and employees of the United Nations, or of any organ, specialized agency, commission or other formally affiliated body of the United Nations, or to the families, suites, or servants of such officers or employees.
Even if the USA removes itself from the UN, it would take some time to negotiate a purchase and transfer of the UN building and the land under it.
To Walt:
Sec 4
No funds are authorized to be appropriated or otherwise made available for assessed or voluntary contributions of the United States to the United Nations or to any organ, specialized agency, commission or other formally affiliated body of the United Nations, except that funds may be appropriated to facilitate termination of United States membership and withdrawal of United States personnel and equipment, in accordance with sections 2 and 3, respectively. Upon termination of United States membership, no payments shall be made to the United Nations or to any organ, specialized agency, commission or other formally affiliated body of the United Nations, out of any funds appropriated prior to such termination or out of any other funds available for such purposes.
Blowing the building up would be dangerous to NYC,
To Walt: NYC is far more dangerous to this country with or without the United Nations.
and would be an act of war on the world.
To Walt: Do you really believe that 185 or so countries would go to war to save worldwide Communism? Most of those countries have no militaries worth mentioning.
Communist countries would not go to war against the rest of the world to save their United Nations. Even if they did go to war in a last ditch attempt to salvage the U.N. it would be the best thing that could happen to the U.S. and its allies whose combined military strength would make short work of China, North Korea, and Vietnam. Hell, today’s Russia might even side with the U.S. rather than face devastation for the benefit of Chinese Communists.
NOTE: The United Nations has been after control of the U.S. military since 1945. Even if the global government crowd setup shop somewhere else, passing H.R. 204 this year would effectively put an end to 75 years of their scheming, planning and betrayals. Lets see them fight their wars without the U.S. military.
Sec 5
(a) Termination.—No funds are authorized to be appropriated or otherwise made available for any United States contribution to any United Nations military or peacekeeping operation or force.
(b) Terminations of United States participation in United Nations peacekeeping operations.—No funds may be obligated or expended to support the participation of any member of the Armed Forces of the United States as part of any United Nations military or peacekeeping operation or force. No member of the Armed Forces of the United States may serve under the command of the United Nations
Even if the rest of the world did not go to war, there would be extreme sanctions that would destroy our economy (and the world's economy).
To Walt: Get real. This country wins a trade war hands down. In case you missed it China’s economy is in the toilet, while the U.S. economy is booming.
To Walt: You got one right. It would be a global disaster for U.N. parasites.
