War is always political.
I was meaning more that a conventional war is more violence then politics. There are various aspects to war, each type has its own balance of these aspects. I just feel that in a guerilla war the politics has as much a part as violence.
Now, Germany was obviously occupied on multiple fronts.
While I can't contest that if a nation of 330 million were to devote its full human and industrial capacity for the purpose of destroying all resistance in a nation of 33 million, it would succeed...
I wouldn't call the richest country in the world failing to convert to a war economy to overcome an enemy ten times smaller then they are to be 'lack of will to win.'
The richest nation in the world should not have to convert to a war economy to defeat an enemy ten times smaller. If it could not; then it didn't want to be there in the first place, it didn't want to do what was necessary to win, or their internal politics is screwed up. Possibly more than one of those.
It was clear then too, but it obvious now that the proto-ISIS "freedom fighter" narrative was completely divorced from reality.
