Inquiring minds want to know: Is it cheaper to stop drugs by building a wall or nuking the opium fields of Afghanistan?

The $15 billion cost of a wall would buy you roughly 750 upgraded B61 nuclear gravity bombs.

Each one can incinerate about 50 square miles.

Afghanistan has about 780 square miles devoted to opium production.

Number of B61 bombs needed: just 16.

Cost $320 million.

Hundreds of bombs left over to enlighten other ne'er-do-wells.

Three pleasant outcomes: 1) Drugs eliminated at the source; 2) Afghan War ends immediately; 3) Drug mules and gangs stop coming over the border.

I say we nuke 'em.
