That looks like someone's high school history paper, first draft….
It was Antifa..no, I mean the far right…no I mean, yeah I agree with GurKhan, it was the Swiss and their evil plotting for world domination…
But more seriously, the idea of the CW in the US was spurned by the Kennan Telegram. It was instrumental in shaping, very quickly, the Cold War ethos, and led, again, within just a decade or so, to the solidification of the US as a ever vigilant security state who saw themselves as the sole global bulwark against those that challenged the liberal economic trading order (note the current US' government's globalist world view is a continuation of this policy-free trade, not free people, dominates those theories).
But the telegram itself was just letters on paper until Stalin green-lit, as Bunkermeister points out, the Korean War in the greatest strategic mis-calculation of all time-Stalin refused to believe the US would fight for Korea. Kennan would have just simply stated "my point is proven."
In effect, the Soviet government increasingly proved Kennan's points (Korea, Hungary, loose ties to communist insurgent movements in France, Italy and Greece that led to open civil warfare in those places in the late 1940's), well before the US took the more aggressive steps that we now know solidified the Cold War (arms race, build up of forces in Germany, defense of Korea, involvement in Vietnam, etc…).
Stalin's miscalculation and Soviet paranoia, which fed US paranoia…and the cookie crumbled from there…and we still pay for it, both literally and figuratively today.
My .02 cents…
checks out some 10/15mm railroad tracks for wargaming.
