An Uncertain World

World War 1 was supposed to be the war to end all wars then 21 years later we had WW2.   In order that mistakes weren't repeated a new world order was put in place underpinned by a marshall plan to rebuild Europe and NATO which joined the US and Canada to Europe in the most successful security alliance the world has ever seen.

It was essentially unchallenged for 70 years until now when we see quite different forces at work threatening to undermine that global security.

Hence "an uncertain world"
