A friend of mine believes that America began to decline as a nation when the military draft was abolished in 1973. I don’t know that I agree. Plenty of experts, it must be said, don’t think the American nation has declined, but believe that much of the rest of the world is simply catching up with us. Others believe our ability to adapt and innovate is as strong as ever.

I can see my friend’s point, though. We no longer have a citizen army, with most young men bearing equal burdens to fight, if necessary, in the country’s conflicts. New recruits are not as likely to come from the class of richer young people, those with privilege, as from those of the less advantaged. The bodies brought back from Afghanistan tend to be grieved by families of lesser education and money.

In a democracy, reality trumps policy. During a time of recognized threat to this country, young people of all levels volunteer for military duty, but they don’t understand long conflicts where even people they are supposedly helping sometimes kill them.

When a significant percentage of American citizens don’t believe in sending troops to a conflict, a draft leads to protests like those during the Vietnam War. If we had a draft today, we might not have entered Iraq and might already have exited Afghanistan. Less advantaged young people would not carry the burden of dying while the richer ones attend college and find lucrative vocations.

What if we passed a law that forbids our country from committing ground troops to a conflict for longer than ninety days unless we first reinstate the draft?
