Manifest Destiny is pretty much that. The US fought Mexico, Spain, and British Canada, exploited the political situation in Europe to buy a huge chunk of land from France, and displaced or killed hundreds of thousands of native people. The US is the 4th largest country by area. Having that much contiguous land is insanely valuable and powerful. By the time the US would have even had to think about colonizing like the Europeans it was going out of style.
