We're facing a national crisis - our military forces are quickly depleting. In addition, we're constantly needing to adapt to new environments and technology. But fear not, I have a solution.
Let's bring back the draft! "What!?!", you say! Yes, let's bring back the draft - but not with geriatric 18-year olds. I say we start the draft at age 4. We shouldn't have anyone older than 8 in the draft. Some might say that this is too young - but I beg to differ. The children are our future. And in the future you're older than the present. Thus, our childer are older than we are.

Besides, having these patriotic young tots run the military provides amazing opportunities. For example, our enemies are already using children in their fight against us. You see pictures of it all the time. 6 year olds carrying AK-47s. It's well known that America's education system is well behind the rest of the world. If their supersmart children are doing it, it makes sense that we do it too.
And when are you most likely to be able to really take a hit and not have it faze you? When you're a child! Kids fall down all the time and bounce right back up. This is a tremendous advantage in battle, as they'll probably be falling into trenches a lot. Also, kids don't mind being messy or wet - also great advantages in the desert or jungle warfare.
Military technology is advancing like gangbusters. It's all basically one big videogame now. And who's best at video games? Yup that's right. I mean really, who would you rather be in charge of new technology - you're stuck-in-the-50s grandfather who can't play Pac-man without a roll of quarters or a someone who can play Halo 3 for 12 hours straight while texting with his other hand?
Kids are fast. Really fast. Way faster than any adult - that's why we have so many runaways. They simply can't be caught.
And having kids in the military also reduces the issue of discrimination. Left alone, most kids don't at all care about gender, race, or sexual orientation. They'd all rather just blow stuff up. Really, babies in uniform would be the ideal situation, but they can't lift a gun! Ahh...Mother Nature, how you thwart us... Imagine the peace that would follow if all babies could wield a Derringer. Sigh...we can imagine can't we? Regardless, this should actually level the playing field and promote equality amongst all.
So, do you want a safe nation for our children or not? If y0u love patriotism and babies, get out there, buy some khaki diapers, and replace that rattle with a howitzer!
