Not so long ago we were told a serious army has now to be a professional and highly trained army. Everything else was useless.
But they seem to plan to just draft young people and fight some sort WWI a bit like the nightmare in Ukraine.
But today Western Europe countries are not Ukraine. If they would engage in a war they would collapse into total chaos very quickly. Those are old, very divided and absolutely not resilient societies.
Just cutting the electricity for a week would collapse the cities. Starting with people putting the buildings on fire because they do not know how dangerous candles are.
"Training" young people for 6 months wouldn't change that.
This is a bit like what happened in WWII when Germany attacked country like Belgium or France. They went right through it because there were a dissymmetry between the German who had it really tough for 20 years and the Belgian or Frenchman at the time.
But the current head of NATO is a former HR at Unilever, so I guess he knows better.
