WHO Headquarters which Trump is abandoning are located in Geneva, Switzerland and for that mater I suggest United Nations which branch WHO is to AS COUNTERMEASURE to also abandon New York City for either Delhi or Beijing.

America demonstrated us how to get really great products and the way to live - standard of living. China demonstrated how to get better for far less and even have Americans prior to import from China place their brand stickers on Chinese products to demonstrate Americans great Chinese quality. American made TV that would normally cost $4000 imported from China costs merely $400 - if...

Its the same with everything else including UN missions, city efficiency when it comes to budget etc...the same and not only with China, but also Russia, India, and others who no longer see the point of paying for super high fees and get in return insulted with racist rhetoric from US president alone. I accent this because US is the main sponsor of UN and along with one others who also host UN offices follow as main "sponsors"... 

Its time to kick-start a United Nations based on social justice and its purpse for which agency was established on 25 April 1945, when 50 governments met in San Francisco for a conference and started drafting the UN Charter, which was adopted on 25 June 1945 and took effect on 24 October 1945, when the UN began operations. 

The main problem with these self hosting sponsors are also their demands that come along super high expenses for foreign missions that non NATO members had to pay out of pocket to participate against themselves I guess.

Yes, after United Nations condemned Donald Trump's mentally unbalanced and unprovoked act of terrorism against Iranian general(3 days ago), lunatic went on revenge power trip by pulling USA from WHO organisation rather than to face consequences of his mindless acts. Its also nice that presidential candidate Joe Biden is eager to bring US back under UN's WHO umbrella, but then again its UN that no longer can afford politic as such even that of main financial sponsor. Politic as such have also demonstrated to entire world American intolerance for existence of other nations and directly contradicts legacy of organisation such as is United Nations. Trumpism is a Hitlerism a terrorism for which Americans should know better before phenomena even appeared in the US. So called "Free Speech" which allows nazi views exercised publicly was prohibited globally worldwide after WWII with exception to the US and for that matter not whole world must pay the price. Unfortunately is so.

UN for lower costs serving its purpose elsewhere and as such affordable to global public is in my view the way to go. Paying super high costs for Geneva/New York city just so global citizens(including Americans - specially Americans and Western European of which many are heavily persecuted against) can read only about its existence on internet when even in need of such services is an option no longer affordable :))) not affordable Mr. Trump not even for the poorest of the poor on this globe.

UN is prestigious organisation, and each country should earn the right to even host one. 

As far as Mr. Trump, it can be seen here that I alone have charged him and US government with acts of genocide which they committed against me naturalized in 2000 as US citizen. Not only about foreign people being killed, but also against US citizens on US soil...Trump is a regular nazi assassin indifferent from those we have seen 70 something years ago - without conscious of any kind who has tendency to run as far as he can get and regardless of how many corpses he leaves behind...

From https://en.wikipedia.org/wiki/United_Nations

Pursuant to the Charter, the organization's objectives include maintaining international peace and security, protecting human rights, delivering humanitarian aid, promoting sustainable development, and upholding international law.[4] At its founding, the UN had 51 member states; this number grew to 193 in 2011,[5] representing almost all of the world's sovereign states.

Having subscribed to a common program of purposes and principles embodied in the Joint Declaration of the President of the United States of America and the Prime Minister of Great Britain dated August 14, 1941, known as the Atlantic Charter,

Being convinced that complete victory over their enemies is essential to defend life, liberty, independence and religious freedom, and to preserve human rights and justice in their own lands as well as in other lands, and that they are now engaged in a common struggle against savage and brutal forces seeking to subjugate the world,

DECLARE:

1. Each Government pledges itself to employ its full resources, military or economic, against those members of the Tripartite Pact and its adherents with which such government is at war.
2. Each Government pledges itself to cooperate with the Governments signatory hereto and not to make a separate armistice or peace with the enemies.

The foregoing declaration may be adhered to by other nations which are, or which may be, rendering material assistance and contributions in the struggle for victory over Hitlerism.

READ:

Human rights

One of the UN's primary purposes is "promoting and encouraging respect for human rights and for fundamental freedoms for all without distinction as to race, sex, language, or religion", and member states pledge to undertake "joint and separate action" to protect these rights.^[114][142]
