> How about taking a non interventionist policy?

Well yea, that is what the parent comment explicitly advocates.

The problem is that US voters are insulated from the horrifying effects of war and thus are not inclined to avoid it.

Thus, the parent advocates achieving non-interventionist policy by giving Americans voters consequences through the draft.

So kind of roundabout, but such is often the only viable way in politics.
