Real leaders lead by example instead of following the bad guy's lead/behavior. And eye for an eye just adds to the body count and doesn't actually solve anything.
Jordan was bargaining for their pilot with an offer of an exchange with captured terrorists and a promise to execute them if their pilot were executed. They had no choice but to follow through.
You bleeding heart Leftwats calling it revenge is just silly. By their own laws, they were fully in their right to carry out the prescribed penalty. Leftwats scream about justice unless it's being applied to their comrades in world evil.
Again, I have said nothing about what Jordan did, didn't do, should or should not do. Jordan's actions are irrelevant to the bigger picture. The issue, it has to be said yet again, apparently, is not executing captives. The issue is destroying ISIS as a political and military entity.
