The EU has the second biggest economy in the world and contains 3 of the G7 nations (4 if you include the UK, which will almost certainly pivot back to EU membership in the next few years). All member states are part of NATO and France, Germany and the UK possess a significant nuclear arsenal.
But yeh, no real power.
PS 500 years ago, the economic power was Western European countries like France, England, Portugal, Spain.
Are you being purposefully obtuse? You could say the exact same thing about Robin Hood.
It just goes to show how England brained America is. What business does America have making movies and TV shows about a 12th Century English folk hero? America hadn't even been discovered in the 12th Century, how can you have context in the US for his actions?
It's a story about a little guy who broke the law to stand up for the greater good while risking his own life to do so. That kind of heroism is borderless. Luigi Mangione may have killed one person but the person he killed was responsible for the death and chronic pain of thousands. I think we English understand that very well indeed.
