Mark Rutte (NATO SG) has Europeans to stop 'dreaming' they can defend Europe without the USA's help.
He sees a move to develop an independent security strategy as likely to fail, because, as he righty points out, it would be very expensive; he suggests 10% of GDP across the EU.
But perhaps this is the 'rupture' that Mark Carney means - time for Europe to be clearer about the expense of defence?
(Which of course is also Trump's line, which may be where Rutte got it from?)
