The Financial Times reports that "the senior US military commander said on Thursday that proposals by Donald Trump to revive waterboarding and target the families of terrorists would be illegal and likely to damage the morale of troops."
"General Joseph Dunford, the chairman of the joint chiefs of staff, did not refer directly to Mr Trump in his comments to the Senate armed services committee. However, asked to respond to ideas floated by Mr Trump about how to combat Isis, Gen Dunford gave a blunt assessment of the proposals."
"'Those kinds of activities that you described are inconsistent with the values of our nation and, quite frankly, I think it would have an adverse effect, many adverse effects,' he said. 'One of them would be on the morale of the force.'”
