Donald Trump wants you to know that there is one leading reason why he is bearing down militarily on Venezuela: drugs.
It is, he has said repeatedly, that country's part in the production and smuggling of illegal narcotics into America that lies behind the ratcheting up of forces in the Caribbean in recent weeks.
But what if there's something else going on here too? What if this is really all about oil?
Watch: Why Trump cares about Venezuela
In one respect, this is clearly preposterous. After all, the United States is, by a country mile, the world's biggest oil producer.
Venezuela is a comparative minnow these days, the 21st biggest producer in the world, its output having been depressed under the Chavez and then Maduro regimes.
Why should America care about Venezuelan oil?
