Yes, NATO is a North Atlantic organization, and two of its members are not located on the European continent.
However most of members, with most of the combined population, are located in Europe.
And when the US think about NATO, they think about their relations with European countries.
Therefore the NATO topic should be located within the Europe subforum.
What is the use of NATO, now that no Soviet armored division risks invading Western Germany through the Fulda gap?
(twenty plus years, and counting...)
..........One NATO to rule them all,
..........One NATO to influence them,
..........One NATO to spy on them all
..........and in the darkness bind them
