It was all about preventing this domino theory that if one country in a region would fall to Communism, the other countries would.

You know, you had the containment theory, that we had to stop Communism from spreading, and the Domino theory that if one country would fall to Communism, then the other ones that didn't happen!

Those events led to a domino effect that has yet to end.

M Theory

a theory. But a theory shared by Moscow.

So, to some degree, it would've been easier for Communism to spread, because people would've known that the US couldn't engage it, but despite of that the Domino theory didn't happen.

The God theory is not just a bad theory.

It's a working theory.

Here's my theory, Andrew.

It was begun with the invention of relativity theory and quantum theory.

If you think you understand quantum theory, you don't understand quantum theory.

So it kind of disproved the Domino theory, especially because after the Vietnam War, the US would not be able to enter another war like it for some time, because the American people wouldn't let it happen.

The theory is generally accepted.

This theory will bear examination.
