Reply #53: Wow, what a list.

Okay, I got 1796, 1797, 1828, 1829, 1830, 1892, 1897, 1954, 1977, and 1979 as the only ten years without fighting. The Apache War from 1851-1890 (40 years) was the longest conflict.

Personally, I was surprised to see how many times we had troops in China. My grade school teachers did not cover any of that.

The problem is there's just too much. If you edit it down to the top 10, you leave out the Spanish-American War, the Mexican War, all the Native American wars, and much, much more.
