The problem here is a nod and a wink until the actions become so outrageous that they cannot be ignored. I say move up the trials in the case of the football players.
In the case of government complicity America trying diplomacy. There used to be a military option called a punitive expedition Reagan did it in Libya and Qaddafi listened. We did not try nation building or risking huge numbers of American Lives.
Bring back the Punitive Expedition as an option in the Realpolitik of international diplomacy, and America will be listened to.
