The US was in a depression at the beginning of WWII. After the high number of deaths in WWI, no one wanted to enter another WW. The prevailing opinion was to allow Europe to resolve its own war.
Many Americans oppose U.S. participation in World War II for a number of reasons:
1) Americans did not want to have anything to do with any more European Wars, as the US went back to isolationism after World War I. 2) Because of a mixed population, it was better to wait for a reason to declare war, as the population was divided in between the two sides.

<h2>Important differences - Unlike the other two, Charles I was not associated with any political Party, and had not "risen through the ranks" to become Leader. As a King, he achieved his position by heredity, and since no-one can choose their parents, this was used to justify the doctrine of "Divine Right" - God dedcides that a child shall be born into a Royal succession, and it is blasphemy to make any attempt to change this. Similarly, it was therefore the "will of God" that he should be succeeded by one of his children - the eldest son, in the English and Scottish tradition. In England, there was also the unusual situation that, as well as being Head of State, the King was also Head of a particular religious organization - the "Church of England" - which meant that he could not be expected to recognise any other form of Christianity. It was his enforcement of this which aroused resistance by such men as Cromwell, who was against any enofrced religon, and for "liberty of conscience". (This was why Cromwell subsequently also opposed Parliament when it attempted to enforce Presbyterianism,) There is perhaps case for seeing a similarity in Stalin, since "Marxist/Leninist Communism" was in fact a "religion", even though a godless one. There are virtually no comparisons with Hitler.</h2>
