The original purpose behind the European Union was simply to keep member countries from starting wars with each other. At the time, competing economically as a unified entity was seen as a secondary bonus.
But now the recent spread of populist nationalism, presidents emerging with autocratic ambitions, the Brexit blow-up in the UK, and Trump’s affection for dictators and daily generated chaos, are all coming together to threaten the existence of the EU… and much more.
Add to this U.S. arms sales to Saudi Arabia, a new Trump dictated military relationship with nationalistic Poland, an unstable Israeli government, a provoked and dangerous Iran, a nuclear-loaded maniac in North Korea, a festering and disintegrating Venezuela, an energized and politically meddling Russia, a determined and aggressive China, a still very frightening Syria, and more… and suddenly you have a world literally on the edge of destroying itself.
All this has been analyzed in past posts. So all I can say now is someone better do something… and quick.
