Yes. NATO. An alliance created against a threat which is no more.

The threat still exists. Just because Communism has died, doesn't mean the Russians do not want empire. The Russian have ALWAYS wanted empire. Putin, the tsars, the Soviet Presidium - none of them are any different.

When - and that is WHEN, not IF - Putin or his successor declares himself God-Emperor of all the Russias and once again invades Europe, NATO will still be quite relevant.

Some of us still remember the massacres of Königsberg.
