The Declaration of the United Nations was crafted in 1942 at the
Arcadia Conference, but the organization was officially created with the signing of the UN Charter in 1945. Both of these events took place in US cities.
At the time the UN was founded, US President Harry Truman's aim was to increase America's participation in international organizations, which is why it was one of the founding members, and the first country to ratify the Charter. Through the creation of the UN Charter, six smaller organizations, called "
organs" were created to handle separate affairs:

Initially, there were 20 members to the Rio Treaty: Argentina, Bolivia, Brazil, Chile, Colombia, Costa Rica, Cuba, Dominican Republic, El Salvador, Guatemala, Haiti, Honduras, Mexico, Panama, Paraguay, Peru, United States, Uruguay, and Venezuela. In 1964, Cuba was suspended, due to its support of communism.
The purpose of the treaty was that in the event of an attack on a member, the other would be obliged to come to their defense, on request.
Nowadays, aside from the occasional implementation, such as the US request for support after the
9/11 attacks, the treaty has fallen into disuse. The Rio Pact influenced the creation of the Vandenburg Resolution, and then, the

Marshall Plan (1948)
In the wake of World War II, several European countries were considered to be in shambles with their economies collapsed. Cities were not able to produce enough goods to trade with resource-producing areas and unable to feed their citizens. The Soviet Union took control of Eastern Europe, which threatened Western Europe.

The Vandenburg Resolution was created in 1948, after the Rio Treaty and Marshall Plan. These previous agreements, supported by the Vandenburg Resolution, gave the US the idea to create a similar collective defense agreement with Europe to prevent Soviet control. It pushed the country to create NATO and demonstrated the importance of international agreements to the country. Vandenburg's draft resolution was introduced to the Senate on June 11, 1948, where it was approved.
NATO (1948)
The North Atlantic Treaty Organization is a collective defense treaty that was created to maintain peace in the North Atlantic region. The treaty included a few features, but the most prominent was the aspect of collective defense. At the time, the US and European nations were worried about the expansion of the Soviet Union. A collective defense agreement would protect nations from being defenseless in the face of a Soviet invasion.
The initial idea for the organization was suggested in the Vandenburg Resolution.
In 1948, the US, the UK, and Canada, began to brainstorm NATO. 12 members signed the treaty in 1949 in

Similar to the other treaties in the period of Pactomania, ANZUS was a collective security treaty, where in the event of an attack on one of the members, the conflict would be settled by peaceful means.
The US deemed the idea unnecessary until the three nations shared their concerns regarding the spread of communism. The idea for the alliance was proposed by the US toward Australia, and was extended to New Zealand.
The alliance has never been formally concluded, but in 1984, when New Zealand banned

This treaty was made to maintain peace in the Philippines and surrounding Pacific region. It is a bilateral defense agreement, denoting that if either of the nations were to be put in danger, the other would be allowed to use military force to come to their aid.
