As long as there have been wars, there have been war profiteers, but never quite like this.

Tonight, new evidence that betters, including a U.S. soldier, may have profited by using inside information

to wager on when and how military operations will unfold. A soldier using classified intelligence

to trade. Unprecedented. There is nothing to compare that to. This is a new kind of insider

trading. For a year, 60 Minutes investigated the theft of Cambodia's cultural heritage,

thousands of sacred stone, bronze, and gold artifacts from religious sites across the country,

leaving empty pedestals where gods and deities once stood.

We found some of them on display at the Metropolitan Museum of Art.

How did these looted treasures get here, and will they ever be returned?

We are on the verge of returning a number of them.

All of them?

That I can't say. I'm Bill Whitaker. I'm John Wertheim. I'm Anderson Cooper.

The War with Iran and the U.S. military operation to capture Venezuelan President Nicholas Maduro have carried the usual hallmarks of conflict. Soldiers, strategy, casualties, cost. But they've also

been accompanied by a new feature, betting on war.

This year alone, more than a billion dollars has been staked online on military decisions and

outcomes. As if they were wagering on football games or Oscar winners, betters all over the globe

have taken positions, some suspiciously timed and with information seemingly too specific

for a civilian outsider, on when and how an attack might happen, even the fate of world leaders.

As we reported in May, it's created a whole new category of insider trading.

As long as there have been wars, there have been war profiteers, but never quite like this.

Cloaked in night shrouded in secrecy, U.S. Special Operations Forces captured Venezuelan President Nicholas Maduro on January 3rd.
