You can get an economy initially rolling with a huge binge of military spending, yes....but then what? What do you do with it? Military equipment, after all, is only good for one purpose which is to smash things up and kill people. If you build more of it, then other countries get scared and they build more it, so then you have to build even MORE, and so it goes. I don't call that a very useful form of growth industry. ;-) So Hitler first of all got Germany on its feet by massive military spending...and then sent the whole country straight to hell by doing the next logical step and fighting a bunch of unwise wars with all that nice shiny new equipment...

Anyone who says you shouldn't do that, though, will be accused of being "unpatriotic" and "unwilling to stand up and defend his country and way of life against a foreign threat"... Ho! Ho!

And there is the magic political prescription for the maintenance of the militaristic lifestyle...where those are are really the attackers pretend that they are engaging in national "defence", as they call it.
