These are fair points and I get it, but the world of today is very different than the world of the early to mid 1900s. Lack of military is far from the only thing keeping Germany from attacking other European countries now. I feel reasonably confident that no matter how many tanks Germany builds, they won’t go rolling into France in my lifetime. What they may do is repel Russia (though even then, I am skeptical that any major nation will attack a NATO country.)
