We’ve been in Afghanistan for 6,000 days. What are we doing? - The Washington Post:

The war in Afghanistan, which is becoming one of the longest in world history, reaches its 6,000th day on Monday , when it will have ground on for substantially more than four times longer than U.S. involvement in World War II from Pearl Harbor to V-J Day (1,365 days).
