Trump’s Greenland brinkmanship leaves leading Republicans rattled

With midterms looming some in Congress have dissented from the president - but it still falls well short of a rebellion

Donald Trump pulled back from the brink on Greenland but not before causing untold damage to the Nato alliance. The US president's sabre-rattling may also have shaken the faith of his own Republican party.

Trump's fleeting threat to conquer the Danish territory prompted the most strident Republican opposition to anything he has done since taking office a year ago. It came on the heels of challenges to his authority over military powers, healthcare legislation and the Jeffrey Epstein files.
