Please tell us your aren’t serious when you’re talking about the British Monarchy as an example of the cohesion in Europe and the West. They should have had their heads chopped off like in France.
Well instead its the Russians who are OBSESSED necrophiles for their tsars. I suggest you look up the details about how the Romanovs were killed.
The American Revolution ironically helped save the British Monarchy...and by God’s grace the institution has evolved into the 19th, 20th, and now 21st Centuries.
