Patronizing rubbish. The EU builds plenty of EVs, rockets and fighter jets and has far more subway systems and public transport than the US.
Europe is already great. It's why hundreds of thousands of Americans moved here in 2025.
As for being a vassal: Trump was warned of the consequences of invading Greenland and he backed down immediately. Some vassal.
The UK itself lost one third of its land area in 1921, following yet another insurrection in Ireland (always a coerced part of the UK subject to genocidal rule and expropriation).
The last straw for the Irish was summary executions of the insurrectionists and the ravages of the Black and Tans -- like ICE but with arsonists and criminals, but without masks. The US will be fortunate if the parallels remain only financial.
