So first let me say it is a great episode and I do like the whole "One little seemingly insignificant act can totally alter the future in tremendous ways" idea.
BUT...........
There is a major flaw in the episode from a historical context.
So the story in predicated on the fact that McCoy goes crazy, enters the time porthole to the 1930's and saves Joan Collins' life and it turns out she starts some big pacifist moment later on which is powerful enough to delay the United States entering WWII, allowing the Nazis to create the atomic bomb first and win the war, totally altering history to the point where the Federation and the Enterprise don't exist.
So, assuming high school history classes have done their jobs correctly, it is true that when WWII started in 1939 the US stayed out of it, at least as a combatant, for little over two years during which time Hitler was kicking ass all over Europe and the Japanese all over China and east Asia. It's also true the reason we didn't get involved sooner was, in part, because many people didn't want to see the US dragged into another World War started in Europe barely 20 years after the first one ended.
The problem though is the US never entered anything on its own volition.....the decision to go to war was made for us after the Japanese attack on Pearl Harbor in Dec. 1941....and Hitler declared war on the US a few days later, like he promised the Japanese he'd do.
After Pearl Harbor no pacifist moment, regardless of how popular or politically powerful they were could have kept the US from entering the war. The Japanese had destroyed a large part of the US fleet and killed thousands in a surprise attack, and then Hitler personally said Nazi Germany would bring the US to its knees. It's completely impossible to believe that our leaders would have gone "Well....let's negotiate longer with Japan and Germany in spite of their actions....maybe we can solve this peacefully and stay out of it." It was no holds barred kill or be killed warfare now and regardless of how people felt on Dec. 6th the United States was in it now until the bitter end.
So it wasn't like the US entered the war at a certain date in reality and because Collins' movement pushed that date back history got changed. Once Pearl Harbor happened the die was cast and no group was going to change it.
Unless Collins' was so influential she got the Japanese government to not bomb Pearl Harbor on Dec. 7th, almost impossible given the closed nature of Japan at the time, there was nothing she or any other pacifist group could do to alter the course of WWII and America's involvement in it. The events were simply out of her hands to influence.
