NATO has gotten flabby, clumsy, lazy and partially deaf. Similar to the UN.
This isn't a new development. Even back during the days of the Cold War, British, French and US forces in FRG were at best a speed bump, a tripwire force whose primary function was to bring France, Britain and the US into the war via the destruction of those forces by the Warsaw Pact armies. And in the case of the Baltic states, there isn't even a tripwire force, meaning there are no armored divisions or air force wings from allied NATO countries positioned there.
To make things worse - Cold War armies were financed by a significant % of each member country's GDP - in many cases, around 5%. The Baltic states aren't even spending 1%. They expect the Russians to not invade, and if an invasion happens, for other NATO countries to do most of the fighting.
In the 60s, once the Russians came through the Fulda gap with 3-4 Russian armies and 35,000 tanks, after the use of tactical nukes, the Russians 1st rest top was 60km behind where I was - 4km from the east-west border. 72 hours later they would be at the English channel.
Nothing has changed.
