Subscribed. This is an incredibly interesting premise. Very interested not only to see how this affects US domestic history. For example, does this lead to a boost in popularity for Franklin Pierce, potentially leading to a second term? Or does one of the military leaders during this war rise to become a popular figure and become president in 1857? Either way, the possibility of butterflying away President James Buchanan and the effect that has on the almost-certain-to-still-happen Civil War is exciting. Internationally, I am incredibly curious to see what effect this war (and the presumed US victory) will have on imperialism in the specific. Will this mean Russia stubbornly holding onto Alaska to keep it out of US imperial hands (with a possible Russo-American War down the line)? And does US involvement in Japan mean that the US also gets involved with China's Taiping Rebellion? Either way, a lot of interesting developments that I am excited to read about. Keep up the good work!
