Of course we still have a lot to do. The point is we have been, for the last half century or so, moving in, generally, the right direction. We live in a time when every single skirmish around the world shows up immediately, 24 hours a day. That provides a skewed view of the world, making people feel like they are surrounded by major conflict all of the time. This doesn't mean we stop trying; it just means that we don't have to lose hope because it feels like an impossible task. Conversely, it also means we need to really need to push to keep from losing ground. We can't go back to what the world was like in the time around WWI and WWII.
