Nor will it do to follow the “Australian model” of a gun buyback program, which has shown poor results in the United States and makes little sense in a country awash with hundreds of millions of weapons. Keeping guns out of the hands of mentally ill people is a sensible goal, but due process is still owed to the potentially insane. Background checks for private gun sales are another fine idea, though its effects on homicides will be negligible: guns recovered by police are rarely in the hands of their legal owners, a 2016 study found.

In fact, the more closely one looks at what passes for “common sense” gun laws, the more feckless they appear. Americans who claim to be outraged by gun crimes should want to do something more than tinker at the margins of a legal regime that most of the developed world rightly considers nuts. They should want to change it fundamentally and permanently.

There is only one way to do this: Repeal the Second Amendment.

Repealing the Amendment may seem like political Mission Impossible today, but in the era of same-sex marriage it’s worth recalling that most great causes begin as improbable ones. Gun ownership should never be outlawed, just as it isn’t outlawed in Britain or Australia. But it doesn’t need a blanket Constitutional protection, either. The 46,445 murder victims killed by gunfire in the United States between 2012 and 2016 didn’t need to perish so that gun enthusiasts can go on fantasizing that “Red Dawn” is the fate that soon awaits us.

Donald Trump will likely get one more Supreme Court nomination, or two or three, before he leaves office, guaranteeing a pro-gun court for another generation. Expansive interpretations of the right to bear arms will be the law of the land — until the “right” itself ceases to be.

Some conservatives will insist that the Second Amendment is fundamental to the structure of American liberty. They will cite James Madison, who noted in the Federalist Papers that in Europe “the governments are afraid to trust the people with arms.” America was supposed to be different, and better.

I wonder what Madison would have to say about that today, when more than twice as many Americans perished last year at the hands of their fellows as died in battle during the entire Revolutionary War. My guess: Take the guns—or at least the presumptive right to them—away. The true foundation of American exceptionalism should be our capacity for moral and constitutional renewal, not our instinct for self-destruction.
