Trump's assault on global institutions, like NATO and the EU, has always matched the position of Putin and other dictators. WHO is a corrupt mess, but the US simply walking away from everything is harmful and cowardly.
The free world still maintains economic, military, and especially cultural advantages, but it refuses to press them and so is losing them to authoritarians who aggressively spread their model.
The UN is a platform for dictators and human rights abusers. Interpol's vice-president is a Russian major-general. Dictatorships fight to control or destroy these institutions, and without US leadership they have been succeeding. Trump is actively helping them.
Trump withdrawing America from WHO mirrors his response to Covid-19: He sees a tough fight and he turns and runs. WHO's biggest donors are the US and Bill Gates and US leadership to reform WHO is essential.
