What were the features of the US colonial policy?

The colonial policy of the United States was indeed different from others. It is worth noting here that they joined the colonial struggle quite late, and in general they themselves were a colony for a certain time. The United States did not act in this regard at long distances, because niches there had already been occupied for a long time. They worked with territories that were not occupied not far from the continent. They acted as follows – when landing on a certain territory, they created their strongholds there, usually associated with military affairs, and from there they already pursued their policy or seized further territories.
