I have wondered for years why Europeans, and the British most of all, have a wild hate boner for Russia, until the other day when I heard the only plausible reason I have ever encountered: European countries are afraid of losing their relevance in the world, and nowhere is this more true than in Britain, which had the world's biggest empire ever just 100 years ago. Russia remains a major power while all of Europe is sinking into irrelevance. In another generation, people will look to China and even India as greater powers, politically and economically, than all of non-Russian Europe combined.
Britain is arguably the hardest hit country in recent times. Quality of life there is becoming unbearable due to oppressive government and endless migration of Muslims who want to take over the culture and society and Indians who also wish to rule from high positions in business and politics.
And, of course, this is a horrible fate. What's happening to Europeans is inhumane. They are being genocided with the participation of their own governments and are not allowed to fight back against their extermination.
In a way, I am more patriotic about and loyal to Europe than to America, even though I am a burger. My ancestry is European (entirely German) and I know our entire civilization is the creation of Europeans and their labors over the centuries. Britain, France, Germany, and Italy have probably done more to shape the world than any other places on earth, with the USA being a heavy hitter but too recent to rank alongside these countries, and Greece being close to the greatness list.
Britain might have the strongest claim of any country to being the most influential society in world history, though the competition with France, Germany, and Italy is fierce.

So, how can we make Europe great again, and I mean truly great? Great enough to rule the world again. And particularly, how do we fix the UK, which is in the midst of utter collapse?

An empire, by definition, is when one ethnic group rules at least one other ethnic group. The ethnic groups can be of different races or the same race, but they have different cultures.
When different groups of people are in proximity to each other, they mix together sexually because the libido is so strong that people, inevitably, will forget whatever taboos there are against mixing just for the chance to have a twenty second orgasm. Ergo, every time different groups live side by side or together, they mix together. No matter how strong the taboo or law against mixing it, the mixing remains inevitable.
Look at the antebellum South, where white masters mixed with slave women, or at the South under Jim Crow, where race mixing still occurred. The sex drive overpowers any taboo or law.
The only way to maintain ethnic, including racial, homogeneity is to remain isolated geographically and cut off from other groups. Living together means mixing together, and since empires bring together different ethnicities or nations in a single overarching political entity, this means empires necessarily become mixed, ethnically.
The original race of any empire is bound to become mixed and bound to disappear. It happened to the Athenians and Romans, not to mention their Bronze Age forebears in the Near East like the Babylonians and Akkadians. It is happening, now, to the British, French, Americans etc.: the modern European empires.
The wages of sin is death. Imperialism is a crime, a sin, and nature punishes it with the death of the original ethnicity that founded the empire.
