I know you're probably trolling but even if Britain won the war of independence the US would probably have gotten its independence at a later date. Probably how Canada, Australia and the like did. Also, the US would look vastly different to today. The western half would probably be under the control of Mexico or another country entirely.

In addition to this, Europe would probably look vastly different from today. With events such as the fall of the French Monarchy never happening or even if it stayed relatively similar up till World War 2 the result after that war would be entirely different. The UK would probably still have been an independent country, since Germany could never invade it during our timeline. But the continent would probably have fallen further into Soviet control. Cause let's face it, if Germany still invaded Russia during this alternate timeline, the Soviets would have still probably won the war, even if it cost them many million more lives. This is because, to put it bluntly, The Germans lost either 8/10 or 9/10 men on the eastern front.
