So we just killed non descrimitory and with out reason?You want to trade a wrong for a wrong? Sin for sin?
Do you know how many more thousands of those people we have killed or been responsible for the deaths of than all of the people that died on 9/11. That had absolutely nothing to do with 9/11.
Should someone be able to hold something (EMP?) over America because of what they don't like but that you have a tangential "responsibility" or connection too? Like... Miley Cyrus? How about the drug trade? US demand for drugs kills far more people than ISIS each year. Should the rest of the world insist that we stop buying drugs and threaten us, even though we have no way of actually doing it?
There are valid reasons we are there, maybe it would be better to let them kill themselves, but there are valid arguments either way. We've probably saved as many lives that been lost. Have we forgotten how many die there anyway from warlords and the hands of their very own governments?
To place all the blame on us as "responsible" is preposterous.
