Thus the advantage of offense, countering the advantages a defense can provide. And mobility in defense can offset some of those advantages.
Regardless, I think defending our border isn't too much to ask, if we are truly serious about defending our country.
We go where they are, we kill them, they don't come here because they're DEAD. That's the plan. Sitting around waiting to be hit is no plan, especially with these guys. If you're dealing with guys who achieve a strategic goal when they blow up a school bus, you literally have to defend everything, and that's impossible.
Lastly, I have to tell you that when I hear folks from the cut-and-run crowd talk about the border, all I hear is "blah, blah, blah." You see, I can't imagine you guys really think any of us who support staying and winning are sitting around thinking "Wow, it's so great that we don't have to defend our borders because we have troops in Iraq." There's no way y'all don't know that without those of us who support the war effort the ruckus that killed amnesty would have been much quieter. So, it really can't be anything more than an empty rhetorical exercise when y'all whip out the border crap, because you'd have to be beyond clueless to think you're making any real point, much less changing someone from open border to border hawk.
