NATO's first secretary general, Lord Ismay, described the original idea behind the alliance in this way: "to keep the Russians out, the Americans in and the Germans down." But now things have changed. The Soviet Union no longer exists, Russia is 1,000 kilometers (625 miles) farther away, and Germany no longer poses a threat. These days, NATO forces are busy in places like Afghanistan (pictured here), but are also having to combat threats that were not even imagined by its original mandate.
