Whose Blood in the Game?
If we had to fight wars the way they did in the Middle Ages, or even in the Hollywood version of the Middle Ages I wonder how anxious these political hawks would be to get us into them. And if the leaders themselves actually had to fight, like they once did, there would probably be no war at all.
Now of course we have no need to bodily engage our enemy. We can fight from afar. With drones. (see article below).
