📖 Pattern of US Intervention in Europe
America's military relationship with Europe began with World War I and became permanent after World War II. Today, the U.S. maintains approximately 65,000 troops across Europe — 80 years after the original threat (Nazi Germany) was destroyed and 30+ years after the secondary threat (the Soviet Union) collapsed. The Ukraine proxy war has revitalized NATO but also demonstrated Europe's continued military dependence on the United States, raising the question: should American taxpayers subsidize the defense of some of the world's wealthiest nations?

🌍 Current US Military Footprint
NATO's 32 member nations collectively spend over $1 trillion on defense, with the U.S. providing roughly 70% of the alliance's military capability. U.S. bases in Germany (Ramstein, Landstuhl), Italy (Aviano, Sigonella), and the UK (Lakenheath, Mildenhall) form the backbone of American power projection into Africa and the Middle East.
Current annual cost of maintaining bases in Europe: $6.3B
