In 1976, two American officers were brutally murdered with axes while trying to trim a tree in the Korean DMZ. America's proportional response? Deploy B-52 nuclear bombers, fighter jets, attack helicopters, an aircraft carrier, and nearly 1,000 heavily armed soldiers to wage the most expensive war on vegetation in human history. It took 42 minutes and millions of dollars to defeat one poplar tree, proving that nothing says "measured military response" quite like bringing thermonuclear weapons to a landscaping dispute.
