It's always difficult to prove a negative—the dog that didn't bark, and how much is the opportunity cost there—but as Dan says, you can see the results of places that fail. There is a logic to democracy. It's not simply an ideology. When you don't have accountability of abusive power, lack of transparency leads to corruption, which leads to injustice and tyranny of majorities, which leads to refugee flows and instability that crosses borders. That has monetary impact. It means we have to pay for more in our security services.
I've worked in the Pentagon. Actually I worked at NDI before but went for 20 years to the Pentagon, and I saw it very much connected not because you impose democracy. That goes too far. That's an oxymoron. As Madeleine Albright says, you can't impose democracy. But you don't want to have to spend so much on security. You'd much rather spend on the preventives, and democracy is a preventive. It promotes human dignity. It promotes human rights, which creates then a self-sustaining and self-corrective inside countries, so you don't have the cross-border impacts that affect our national security, that cost billions of dollars rather than the millions that typically go into democracy work.
