The Bundeswehr is, I think, a break from the past mistakes of the German government and its armies. The modern tradition insists on the subordination of the Heer to the civilian government as well as a duty to act with righteous and honor. Well, OK, who knows what will happen in the future? But it's a start.
And as for the power of the Bundeswehr, well, for the love of Pete, if you're going to have an army make it a good one! If the government does its job, the better the army, the fewer people die.
I'm not so stupid as to think that we'll get rid of armies anytime soon. But I already see that many countries have learned the foolishness of going to war. If we have to have armies for the next 100 years, I hope that all of the servicemen and servicewomen will spend 99% of their time being bored.
