UNO: What is it exactly?

The United Nations Organization (UNO) is known for bringing countries together to promote peace and cooperation. It was set up after World War II on October 24. Since that time, this holiday is observed annually, where members get together to discuss global issues and work out solutions. The UNO encourages countries not to give up when they ran into obstacles. 

Thus we came together on the English Practice and talked about different organizations who support the world and global issues, we looked through some advantages and disadvantages, we read an article to find out more details about their mission and learned some common phrasal verbs according to the text.
