America's military leaders, in their infinite wisdom, saw fit to use a MOAB — "Massive Ordnance Air Blast," also known as the "Mother of All Bombs" — in Afghanistan against ISIS forces.

One benefit of having Donald Trump as president is that now it suddenly matters how much it costs to bomb foreign countries. The Twitterverse, thanks to Russian defector Edward Snowden, quickly came up with a price tag of $314 million.

But in fact this was the cost of 20 such bombs. So a MOAB actually costs about $16 million.

When Obama was president, it cost only $1.1 billion to turn Libya into a failed state and a humanitarian disaster without a legal congressional authorization.
