Football and war

I'm a pretty big football fan. Although I opted to devote all of my time as a youth to playing baseball, I've been an obsessive Packer fan since I was around 4 years old. One of my earliest memories is jumping on my dad to recreate a running play I had just seen during a Packer-Viking game. So although I didn't play the game, I do understand it very well. One of the basics in football is "winning the line of scrimmage". You win the line of scrimmage when your linemen are consistantly on the other guys side of the line on running plays, and when offensive linemen are keeping the opponent out of the pocket on passing plays. Homeland defense is pass blocking. You have no choice but to defend against your opponent on your side of the line. You want to keep your opponent from getting to your most important player, the quarterback. In homeland defense, you have no choice but defend against your enemy on your own turf. Your goal is to keep your enemy from hurting your citizens and your infrastructure. Anyone who knows football also knows that if you pass block on every play, bad things are going to eventually happen. Run blocking is like war on foreign soil. You get the other guy occupied on his side, on his turf. When you push him backwards, it makes it much more difficult for him to hurt your ball carrier, especially behind the line. To propose that we should only look at homeland defense, that we should only look inward, is like saying they should only pass block in the NFL. You are going to lose the war (game) if you take that approach, because your enemy is going to be able to come at you with his ears pinned back.
