We don't do a lot of good news posts, but I have one for you now. COTTonLINE's favorite writer on foreign affairs, George Friedman, looks at the likelihood of a world war happening, and concludes it is unlikely.
He is reacting to a colleague's contention that such a war is either immanent or quite likely. You will enjoy his categorization of both the fighting in Ukraine and the tensions in the South China Sea as not rising to the level at which nuclear war becomes likely.
Friedman's analysis makes sense, I hope he is correct. However, hope is a lousy basis upon which to plan.
I side with Roman general Vegetius who wrote, Igitur qui desiderat pacem, praeparet bellum which translates as "Therefore let him who desires peace prepare for war." or the modern version which is "If you want peace, prepare for war." Make the effort to be ready for war, while enjoying the ensuing peace.
