What is an issue that the US and the united nations have disagreed about?

One significant issue of disagreement between the U.S. and the United Nations has been the approach to climate change and environmental policy. The U.S. has often taken a more cautious stance regarding international agreements, such as the Paris Agreement, prioritizing economic concerns and national sovereignty. In contrast, the UN has consistently advocated for more aggressive global commitments to reduce carbon emissions and combat climate change. This divergence highlights broader tensions between national interests and collective global action.
