Donald Trump: It’s ok to kill militants’ families

White House hopeful would reinstate waterboarding if elected.

Republican presidential frontrunner Donald Trump says that if he became president, he would reverse laws that prohibit waterboarding and other harsh interrogation techniques, arguing that banning them puts the US at a strategic disadvantage against Islamic State militants.

Trump has articulated a loose, but expansive set of principles, which, if enacted, would be a fundamental shift in the strategy the Obama administration has employed to fight violent extremism.
