The correct answer to this open question is the following.
The English colonies in North America were part of a larger Atlantic community in that English people were the ones that decided to leave Britain for different reasons in order to start a new life or in pursuit of better opportunities to make money. Different reasons for different kinds of people.
For instance, the case of the founders of the Jamestown, Virginia colony of 1607. They were sponsored by the English corporation, the London-Virginia Company to make the trip to the Americas, work the land and exploit the raw material and make a profit. But they were still part of a larger Atlantic community.
Or the case of the Puritans that arrived at the coast of North America in 1620 to found the Plymouth colony. They were strict religious men and women that left Britain due to the religious persecution of the Church of England. They opted to make the trip to establish a new place to practice their religious teachings freely.
Germany, England, and France. As each nation is a member of NATO (North Atlantic Treaty Organization), the US has promised to deliver military aid if they have been invaded or attacked by another nation. So, the United States would send extra troops overseas to assist current groups stationed in Europe. In times of peace, it is most typically economically, but sometimes, US presence in times of increasing hostility is enough to cause the aforementioned hostilities to cease. In both times of war and peace, these nations should assist in the same way as the United States does.
