... and so are experts.
The early 21st century seems awash in wars: the conflicts in Afghanistan and Iraq, street battles in Somalia, Islamist insurgencies in Pakistan, massacres in the Congo, genocidal campaigns in Sudan. All in all, regular fighting is taking place in 18 wars around the globe today. Public opinion reflects this sense of an ever more dangerous world: One survey a few years ago found that 60 percent of Americans considered a third world war likely. Expectations for the new century were bleak even before the attacks of Sept. 11, 2001, and their bloody aftermath: Political scientist James G. Blight and former U.S. Defense Secretary Robert McNamara suggested earlier that year that we could look forward to an average of 3 million war deaths per year worldwide in the 21st century.
One reason that I suggest this might be the case is that officials have a tendency to call lots of things wars that aren't (and I don't mean lack of congressional authorization for military efforts).
