Dear brothers of Republic of Korea Army, Firstly, I am very happy to see your Army developed and become braver and braver than ever. However, my brothers, I know that there are some of our brothers are forgetting our mission: to protect justice, our nation and our citizens, our families. Please do not forget it, please. Your noble nation must be protected from the communism. That is the most evil thing on this world. If you fail, your nation will be lost; your country will be poor. The mind of your beloved people will be controlled.
Brothers, I know that you are living in good conditions and you are forgetting the war; there are even some people turned to love the communism. But please don't. Please remind yourself everyday that the war is never end; and that if you want peace, you must be ready for the war. Please! Brothers, I know that you are asking where I come from and why I am writing these lines with my blood and tears, for people and army of another country, another nation. I come from Vietnam, you know Vietnam now, right? A country under control of a communism nation. Right here, there is only one party to vote; history are lies; mind of people is controlled like in China. Houses of people can be destroyed to build villas for mandarins, and so on. Everything is the same like in North Korea, except we can trade and go to many place easier, and have more channels of TV to watch, have more music to listen. And right now when I click button "Post", I know that I am not in the safe zone anymore. It is quite clear for you to understand, right? I hope so, brothers.
And you know the reason made my country like that? Briefly...We had a republic, too: Republic of Vietnam, like your nation: Republic of Korea. But we did not save it although your President Park Chung Hee tried to help us much. In 1975, almost of our people trust the communists. And, we lost. We lost our nation, our freedom. You lost an ally. My young brothers, I hope that after know about us, please ask someone old in your family about us... I hope and I need to know that our close ally has not forgotten us... And, do not forget to protect your nation from the devils... God bless you, R.O.K, our ally. A Republic of Vietnam Ranger, R.O.V Ranger Corps, Republic of Vietnam Army
