<h1>US president denounces UN as ineffectual while pledging America First: expanded fossil fuels, tighter immigration, tariffs, military threats</h1> The US president addressed the UN General Assembly, sharply criticizing the organization as ineffectual while affirming continued US support, and promoted an 'America First' agenda emphasizing expanded fossil fuel production, stricter immigration enforcement, and rejection of green-energy policies. He threatened military action and new tariffs to influence conflicts, opposed recent moves recognizing Palestinian statehood, and claimed credit for mediating multiple conflicts. The speech signals potential shifts in US foreign policy and multilateral engagement, raising legal and diplomatic implications for international institutions, treaty cooperation, sanctions, and state-recognition dynamics.
