A way of taking tea - NATO Standard tea is with milk and two sugars.

Standing for the "North Atlantic Treaty Organisation" which stood united against the possible expansion of communism under the Soviet Union and the Warsaw Pact.

The Germans seem willing to do recon but not a lot more. God knows what the French are up to (and frankly who cares)! Looking back, they probably might have sent some troops from the Foreign (i.e. expendable) Legion, but the Americans ballsed that up by being a little less gracious than one needs to be to elicit co-operation from this moody (and very slightly cowardly) people.
Also called OTAN in countries were Johnny Foreigner is in charge.
