In August 1964, the US naval destroyers were attacked by several torpedoes on the Gulf of Tonkin of Vietnam. With this case as a start, the USA started intervening militarily in Vietnam. Later, it became clear by the New York Times that the USA fabricated that incident. Americans are sometimes violent, and their government often makes fatal mistakes. However, we should remember that the mistakes made by the US citizens were always criticized by the US citizens themselves. In my opinion, it is the reason why the US citizens are great.

By the way, I want to mention the name Gulf of Tonkin. Today, Vietnamese people don't use the Chinese characters basically. So, they may not know that the Chinese characters used for Tonkin are 東京. 東京 is pronounced as Tokyo in the Japanese language, and of course, it means the city that is the Japanese capital. In front of Tokyo, there is a bay called Tokyo Bay. In the Chinese-character culture sphere, bay and gulf are a single word, 湾(wan). Put simply, the Gulf of Tonkin and Tokyo Bay have perfectly-accordant characters, 東京湾.

東京 means "an east city" or "the east capital". It is a proper noun, but those Chinese characters are used generally. In Japan, China, Korea, and Vietnam, there were a lot of 東京. 長安 Changan (the current 西安 Xian) was the capital of the Former Han and the Tang Dynasties. The capital of the Later Han Dynasty was 洛陽 Luoyang. These cities and Beijing and Nanjing are historically the Chinese capitals. Luoyang was often called 東京(Donjing) because it is in the east of Changan.
