The greatest global security threat of the 21st century is the United States of America's fear of losing its status as the world hegemony. From this fear precipitates actions - in the name of "strategic manoeuvring" - that have destabilized, to name only the latest places: Iraq, Libya, Syria, and Ukraine. Ukraine represents exactly the kind of overreach, on the United States' part, that may result in the unthinkable.

This is the top tier of global security threats, all other threats should be viewed through this prism. It is also not necessarily that America is evil, Thucydides writing in the 5th Century already showed that all pre-eminent powers will behave this way. The only difference now is that a war fought to maintain such a hegemony will be the last war.
