There're a variety of policy tools short of U.S. intervention that actually could have been applied and that might well have deterred a serious amount of killing. Again, we will never know whether denouncing the perpetrators in the early days of the genocide and declaring that we were going to set up a tribunal to prosecute them; or freezing their assets, so they understood that there wasn't going to be any bounty on the other side of this; or patrolling from the skies and trying to deter just by our presence; or really earnestly going to African countries in the early days rather than waiting two or three weeks -- just so many things that could have been done that weren't done.
