You referenced Vietnam and Korea.
You are right. There was no domino effect. Communism is harmless, it does not spread. China is not our enemy, it is our friend. And Truman was one of the best presidents around for stopping Patton in WWII and MacArthur in the Korean war for wanting to put an end to communism altogether.
The best thing we ever did was send all of our manufacturing capabilities to Communist China so we could buy everything from them which allowed them to build a very large and modern military that is currently threatening their Asian neighbors and infiltrating our country.
The above was written with extreme sarcasm.
I'm so happy you agree and see "the truth." Oh sure, the commies took over the world after we tucked our tails and ran in Korea and Vietnam which was after sacrificing thousands and thousands of young American lives. How many commie countries are there today? Yep. It really spread like wildfire. Just like there were WMDs all over Iraq!
China is not our enemy, it is our friend.
Has China attacked the US? Don't you see the pattern? First, you create a monster/enemy (Korea, Vietnam, Iraq, Russia), and then you send out the troops. Now, some poor gullible souls like you seem to believe the story fits like a hand in a glove. On the other hand, if you follow the pattern it is quite obvious most of you are being led around like a camel with a nose ring into oblivious slaughter.
We've been able to get by with our bullying for decades, but now the rest of the world is growing up, and they see it -- and they don't like it. BRICS and the Shanghai Cooperation Organisation are perfect examples.
We had a good run, but like all empires in history, sooner or later, they wane—the British Empire, the Spanish Empire, the French Empire, the Roman Empire, the Greek Empire, the Persian Empire, and on and on. Only a fool thinks we can avoid the same fate.
I understand you are being ironic. What I say is: Well, it spread to Washington DC. What domino fell on the United States?
Seriously - WE are the global color-revolution (neo) Marxist empire now, at war everywhere abroad, with an aggressive DOJ/KGB censorship and political-control regime at home
