50 years ago, you can kill blacks; 100 years ago, your could kill your wife; 200 years ago, you can kill someone over an argument; 400 years ago, you can kill someone because they are acting "strange". 800 years ago, you can kill someone because they had spoken out of turn. 1600 years ago, you can kill someone because it makes for great entertainment; after that, well it's simply, "Me Igor! You take food from me, I kill you".
How can anyone ignore how far we'd come over the centuries? We are morally stronger NOW than ever before; it doesn't seem that way because people are paying more attention to NOW, instead of comparing "NOW" to "THEN".

To answer your question, pay attention to what's going on in Iran, N. Korea and Russia. Most important, pay attention on how we handle those situations.
