To find examples of situations where the United States has relied on international organizations like the United Nations (UN), Southeast Asia Treaty Organization (SEATO), and North Atlantic Treaty Organization (NATO), you can start by conducting research on each organization individually.

1. United Nations (UN): The UN is a global organization that aims to maintain peace and security, promote social progress, and coordinate cooperation among nations. The United States has relied on the UN in various situations, such as:
- International peacekeeping missions: The US has participated in UN peacekeeping operations, providing military personnel and resources to help maintain peace in conflict-ridden regions, such as in Bosnia and Herzegovina, Somalia, and Haiti.
- Addressing humanitarian crises: The US has often collaborated with the UN to respond to humanitarian emergencies, such as providing aid and support during global disasters or conflicts, including the response to the 2010 Haiti earthquake and the ongoing Syrian refugee crisis.
- Sanction enforcement: The US has relied on the UN to enforce economic sanctions against countries involved in activities contrary to international law, such as North Korea and Iran.

2. Southeast Asia Treaty Organization (SEATO): SEATO was an international organization that aimed to prevent the spread of communism in Southeast Asia during the Cold War. While SEATO is no longer active, the US relied on this organization in the following situations:
- Vietnam War: SEATO was invoked to provide a justification for US military involvement in the Vietnam War, as the US claimed it was upholding its obligation to assist SEATO members against communist aggression.

3. North Atlantic Treaty Organization (NATO): NATO is a military alliance between North American and European countries that was established to create a collective defense against potential threats. The US has relied on NATO in various situations, including:
- Afghanistan: After the 9/11 attacks, NATO invoked Article 5 of its treaty, which states that an attack on one member is considered an attack on all, leading to the deployment of US forces alongside NATO allies in Afghanistan.
- Kosovo intervention: NATO played a significant role in the intervention in Kosovo in 1999, where US-led NATO forces conducted airstrikes against the Federal Republic of Yugoslavia to prevent ethnic cleansing and establish peace.

Remember that the examples provided are just a starting point, and further research will provide a more comprehensive understanding of how the US has relied on these international organizations in various situations.
