Donald Trump threatens to repeat US errors on world stage

If Noam Chomsky was right when he said, after George W Bush invaded Iraq in 2003, that America was the greatest threat to world peace, then that threat may have just increased twenty-fold.
Donald Trump’s triumph creates a nightmarish scenario, one whose contours and repercussions we can only guess at. A loose cannon, a vain, unpredictable man, will soon occupy the Oval Office, pledging to “put America first” and “make America great again”.
