There is another similar idea here. "All I want is peace so give in to every one of my demands and we can have peace, after all isn't that what we both want. Only a warmonger would resist me."
That's exactly what I hear when I hear a leftist or Jihadist talk about wanting peace. Their idea of peace is that we give up and let them walk on us. "Who speak peace with their neighbors while evil is in their hearts." (Psalm 28: 3)
We could have had peace in the mid 20th Century. All we had to do is surrender to Hitler. (I know it's beating a dead horse, but I consider Hitler a leftist because he believed in a state-run economy and wealth redistribution.)
Those who want peace at any cost will be a terrible price for it, and then will probably not get it. Those who have a price they are unwilling to pay for peace will ultimately get it at a much lower price.
