I still cannot belive that my country is using MiG-21 as their primary fighter jets. This plane was introduced in 1959 so you can imagine how 'high-tech' it is. I was amazed to find out that countries like Cuba, Eritrea, Ethiopia, Uganda, Zambia or North Korea are using the same fighter. Even if this plane is ancient for our times, european countries like Romania, Bulgaria or Serbia are still using it. What do you think about this? Do you think that NATO should force this countries to upgrade their Air Forces?
