Why The UN

The United Nations is indispensable to tackling humanity’s greatest challenges and driving global progress. Created out of the ashes of World War II, the UN works to unite countries against their greatest threats and in service of their highest aspirations. In its over 70 years, the UN has helped reduce conflict and maintain peace around the world, alleviate poverty, advance human rights, and deepen cooperation around shared purpose. As our world grows more connected and threats more complex, the UN remains essential to driving global progress.

Because of the UN:

  • Smallpox has been wiped off the planet
  • Stability has returned to war-torn countries
  • The hole in the ozone has healed
  • Millions of children are protected from disease
  • Human rights are enshrined in international law
  • All 193 Member States came together to agree on 17 Sustainable Development Goals – humanity’s blueprint for a better world by 2030

The United States led the creation of the UN over 70 years ago because it understood even then that countries are stronger acting together rather than alone to face challenges. See how we work to advance that vision.

The UN was created for all of us – We the Peoples. We all have a role to play in supporting the UN’s work, and anyone can help the UN create a better world. See ways you can get involved.
