Belgium had a law that bascially said that we could prosecute people for crimes that were committed by non-Belgians on non-Belgian soil.

There was a good reason for us to have this law. It had to do with certain incidents in Congo, 15 or so years ago. We had the means to prosecute, as well as the opportunity. We just didn't have legal infrastructure to do so. So an umbrella law was approved rapidly.

Sometime later, people came to their senses. They abolished it some time ago (or reduced it), much to the displeasure of the leftists who were (their own words) 'proud that we had such a progressive law'.
Yeah. As if it could be used on a general basis. It would have been hilarious, had someone filed a lawsuit against dubya or another leader of an international power.
