Even with China taking extreme measures to contain the spread of the coronavirus — effectively quarantining 50 million people in the center of the country — more than 200 Chinese have died and it is beginning to pop up around the globe, including at least six cases in the United States.

This is one of the few times when there are advantages to being an authoritarian society where people are used to immediately obeying commands from higher authority; imagine the reaction if the U.S. government shut all transportation in and out of Chicago, a step the Chinese government has taken in a similarly sized metropolis, Wuhan.

Are we facing another Spanish Influenza, which a century ago infected more than a third of the world's population with a 20 percent mortality rate? Probably not.

And if this or a future virus truly goes global, the world's militaries are going to have to take a lead role in containing it.
