As regards to the issue of the American Revolution.
This was a popular revolt against Tyranny. Not a bunch of hotheads who decided that they didn't like the way things were run and decided they were right and used violence to impose change against the will of the people or its lawfully elected Government. As the population had no ballot box to vote with, and was this THE issue, they were left with little option after they asked nicely. BTW As I recall the American Revolution was fought by one group of 'British' subjects against another group of 'British subjects. Sides were taken and the 'British' colonists squared off against each other. Remember, George Washington was an Officer in His Majesties Army.
Mad King George (a Kraut) refused to acccept that the wishes of the 'British' Colonists were reasonable and ignored Parliament who felt they were. When he found it hard to get the 'British' army to do his bidding or stop siding with the other 'British' colonists, he hired German Mercenaries from Germany to do his dirty work.
King George is still sneered at as 'the Mad King who lost the Colonies'.
Having said that, If King George HAD listened to parliament, you would now own the 51st State of 'England', Parliament would sit in Washington, you would have a Queen as Head of State and be watching the Changing of the Guard at the White House Palace instead of Buckingham Palace and we would not be having this argument. .
