Knowing that the W. Bush Administration swindled US citizens into going to war with Iraq isn't enough for us to demand revenge such as putting members of the Bush Administration on trial as war criminals. But then only a the small percentage of US citizens in the military were effected. It hasn't all played out. There could and maybe there already were small acts of revenge.
Global warming is effecting everyone and in the near future everyone will be looking for folks to blame it on. In the political sphere a few Democrats and many Republicans will be low hanging fruit for those looking for revenge. Outside of the political sphere who knows what millions of unbelievably desperate people in this extremely well armed country will do. God help us.
