Or rather of one Russia, Tsar Alexander II, who let his feelings of anger lead him into the worst decision in the past 500 years of history and a decision that would cost over 100 million lives. That fateful decision was made in 1861.
What was the main event of 1861, that so drew a decision whose results would not only reverberate through but shape to the core the 20th century? Was it the conquest of Mexico City by Porfirio Diaz? Or the patenting of the flush toilet by Thomas Crapper? Or maybe the abolishment of serfdom by the very same Alexander II? No, not that or the dozen other such events, but the opening of the American Civil War.
The fateful and short sighted decision of the tsar was to side with the Federal US government instead of the Confederacy. If all truth be told, Imperial Russian culture was much closer to gentile Confederacy than the industrialized, indentured North. However, the Confederacy had to benefactors who were unpalatable to Russia at that time: England and France. While mostly on rather than off Russian allies, at that point, only 5 years had passed since the end of the Crimean War, where both of these powers had allied with the Islamic and blood thirsty Turks against the Orthodox Christians and the Russian Empire in particular.
It can be understood that the Tsar had much angst about finding himself on the same side as these two enemies and thus made the decision that would doom the Empire and several others and would lead humanity to the sorry state that it is in today, on the brink of yet another global financial disaster and possible multiple wars.
No other decision made by foreigners had such a powerful influence on the out come of the American Civil War. By siding with the North and placing his fleets into New York and San Fransico harbors, Tsar Alexander II issued a direct threat to both England and France that intervention, that is recognition or more, of the Confederacy would lead to war with Russia. This doomed the Southern effort in the long run and thus also the Russian, French, British and German Empires with it.
But what would have happened if Russia had stayed at worst neutral or at best allied with the Confederacy?
Well for one, the Confederacy would have won her freedom. The North would have been morally and politically defeated and economically damaged, damage that would have taken a several decades to recover from. During this time frame, more than likely, the weakened Union would have been drawn into the orbit of the rising German star, as the Union would have needed allies against the combined might of the Confederacy to the south, Mexico also to the south, Britain and her Canadian holdings to the north, Russia to the west and France to the east.
Spain would have still lost her last Carri bean holdings, Cuba and Puerto Rico, to the Confederacy which would have annexed them. But Spain would have continued to hold Guam and the Philippines, at least until the rising star of Japan ripped them away from it.
The main question, though, would have been: what would have happened when World War 1, the Great War, started? Well obvious enough, Germany and the Central Powers would have won. But would that have been such a terrible thing? To begin with, this was not a war of ideology and this was not Germany under Hitler of the late 1930s.
The Union would have more than likely been allied to the Kaiser and would have found itself in a two front war, with British Canada in the north and the Confederacy and more than likely Mexico to the South. Russian fleets out of Alaska would have raided too. Thus though, not only would the Allies not receive fresh Yank reinforcements in 1916, but instead would have been fighting them. Britain would not have been able to draw on Canadian support either and would have had to instead divert troops to defend it. As such, the Central Powers would have surely won.
So now what? What would have happened? In North America, Canada would have more than likely fallen to the North, but the Confederacy would have survived. With the technology of the day, the Confederacy on the defensive, with powerful rivers and mountain ranges and deep forests as barriers would have ground the North to a stand still.
In Europe, Germany and Austro-Hungary as well as their Bulgarian and Turkish allies would have gained land, mostly at the expense of north eastern France, an annexed Belgium and Netherlands, parts of northern Italy and southern Romania and Russian Poland.
Key to everything would have been the avoided collapse of the Russian Empire and the destruction of the Marxists. The Russian civil war would never have gotten nearly as far. With Wall Street allied to Germany and much much poorer than what was the reality of 1917, the Bolsheviks would have been hard pressed for funds. At the same time, there is absolutely no way that the Kaiser would have allowed the Marxists to sit on Russia's throne. That would be reserved for either one of the Kaiser's Romanov cousins or for some Germany prince who would have become a Russian nationalist anyways.
Thus the whole foundation of World War 2, the Cold War and the various wars and crusades since, would have collapsed. As well the Islamic Arabs and their Jihads would never have been started either and Islam would have been kept in check both in the Middle East and in Europe, where nationalistic and Christian Kings, Kaisers and Tsars would have been loath to allow them in, unlike the Trotskyte Marxists who are the masters of the modern and dieing West.
Yes, Union victory was the worst of all things to happen to the world and Alexander II in his shortsightedness on the subject, more than anyone facilitated it's happening.
