Fighting words of 54/40 or fight were echoed by many, but eventually Britain, Canada and the United States agreed on a boundary for Canada and the U.S. in the north. After a war or two and other disagreements, Mexico and the U.S. finally came to a satisfactory deal on the southern boundary of our country. We had smaller yet still bloody disagreements with Spain for Florida and eventually between our selves and ended up with a bloody Civil War. After this war, we grew and grew rapidly. Railroads were coast to coast and people had the ability of easily, for the time, to go west and do so rapidly as well. We got messed up in others business in Central and South America and the Monroe Doctrine came about and until today has remained in effect.
We found ourselves with foreign countries as colonies, but we finally gave those who wanted it - freedom the Philippines come to mind. Almost immediately after WWII, we granted them their independence and they then fought a faction of their people who wanted something different from Democracy. We made mistakes and did not become the benevolent country to our Native Americans as we should have and herded them into reservations. Ended up a world power like it or not and fought and won two wars in Europe and the East and saw many more world countries get their freedom and many lost it or didn’t take to it even today. We have stuck out noses into some areas we should possibly not have done so, but we always felt we were doing what was for the best.
During this time we also gave a home to millions of people from other countries, people who wanted what we had, freedom and choice of how to live. We have made mistakes on the way and still are, but we tried, found some things good others bad and kept the best tossed the bad. We have allowed many others into our country, sometimes many that we should have possibly been a tad more concerned about. We fought a Cold War and won over the powers of Dictatorship and then found ourselves in a fog of peace. We have done some good things, some not so good, but we have done and learned and hopefully will continue to do so. We have found ourselves in a position of being a world power, a super power, a country not to trifle with.
