Is the UN headed for financial collapse without US support?

The United States has not paid its United Nations dues in over a year, creating a severe financial crisis for the international body. This withholding of funds, amounting to nearly $4 billion, has led UN Secretary-General Antonio Guterres to warn of a potential "financial collapse." The situation could force the cancellation of the annual General Assembly and even a shutdown of the UN headquarters. This occurs while the US continues to exercise its veto power, notably blocking resolutions on the war in Gaza, and has withdrawn from numerous multilateral organizations.
