Is the Domino Theory Valid?
I come from a generation that has largely been taught that, no, it is a false theory. But the real truth is that it is sometimes true, sometimes false.
With Hitler, the theory was valid. Hitler was committed to divide and conquer. Giving him success in Austria set him up for success in Czechoslovakia. Giving him success in Czechoslovakia set up his attack on Poland. Standing up to Hitler in August of 1938 would have stopped him. The German army was on the verge of turning against him. Giving in made Germany much more dangerous. The cost of starting to stop Germany in 1939 was vastly greater than the cost would have been in 1938.
Against the Soviets during the 1920’s through the 1980’s, the theory was false. Even though they were expecting and working toward World Wide Communism. Then why was the Domino Theory false in this case?
Because a quirk with the Soviets. Karl Marx and claimed that Capitalism will inevitably collapse on its own. That the working people will see the advantages of Socialism eventually and when they do so, bring down the Capitalistic States. And the Soviets believed this fairy tale. So, they were content to let this happen. Why risk a big war. Even if the war is successful, they would rob Marx of the glory that he deserves, to show that his prophecy was true.
I was taught that the Soviet Union was a very dangerous enemy. In truth, having an enemy who is largely content to wait for you to fall apart is not the worst enemy one can have, however powerful they may be. With enemies like that, who needs friends? But Russia has learned that Marx was a false prophet. If Russia is going to take over central Europe, they are going to have to make it happen. So, in that sense, Russia is a much more dangerous opponent than the Soviet Union ever was, however much weaker their conventional military may be.
But, in general, with a powerful state that wishes to expand, this theory is true. Unless they believe in fairy tales.
The Domino Theory is not true with China, I do not believe. Unless I am mistaken, China just wants all the lands it historically controlled. Hence, because the Mongols controlled China, and Tibet, China, in a sense, controlled Tibet in the past and so they must control it now. If they take over Taiwan, I think that would be it. Still, this should be resisted.
The Domino Theory is not true with North Korea. I think that if the threat of nuclear weapons allowed them to overrun South Korea, they would stop with that.
But Russia is a different matter. It is like China. It wasn’t to control what it used to control. So, Ukraine would not be the end of the story. They want Ukraine, the Baltic States, Finland, Poland and Germany. And possibly a bit more. So, it won’t stop with Ukraine. Success in Ukraine will only encourage them to go further.
So, no, the Domino Theory is not always false. Or true. But in the case of Russia, it is true.
