That's humans for you... We never get satisfied and we just choose not to learn from history. As far as I'm concerned, war is totally pointless because the people who start them do so for selfish reasons. Nations go to war for vain things like resources and lands. Yet, if you look at the people they lead, they're still suffering. What then is the point? Why does peace look so farfetched?
Honestly, I don't think humanity has any hope. Because most leaders today are more interested in keeping their power by any means necessary, regardless of how many people will end up dead than they are with keeping peace.
Economic sanctions can't work either because you can't force these guys to do what you want. Also, any physical action one leader takes against another, regardless of how noble the reason is, would be a declaration of war.
And at this time, everyone is simply looking out for his own people. That was the same stance the US took before Pearl Harbor and it was forced into the war as well. It seems we're all sitting on a powder keg that will most likely go off any time soon, but we're all waiting for the last possible moment.
And I also believe that the rest of the world is watching the US. Because the decision they make would determine how everything will play out.
These are dark days indeed... God help us all.
The point of war is to maximise wealth and power for those who wage it.
Up until that point, they were selling to both sides.
