How did john calvin’s ideas take the main root in the american colonies?

Primarily puritans went to the new world at first, and since they took a lot of Calvinist values, and they were pretty much the only Europeans there at the time, their word was law until more people got there.

america opposed the axis powers, because they knew that the united states would be targeted during the war. not only that, but germany (which was an axis power) broke the treaty of versailles, and started developing an army, and started attacking and taking over countries. furthermore, japan, which was allied with germany and italy (who both were axis powers) was attacking china, which was a great ally to the united states.
