Republican foreign policy veterans rebuke Trump worldview

More than 90 Republican foreign policy veterans have pledged to oppose Donald Trump, saying his proposals would undermine U.S. security, in the latest sign of fissures between the Republican presidential front-runner and the party establishment.  “Mr. Trump’s own statements lead us to conclude that as president, he would use the authority of his office to act in ways that make America less safe, and which would diminish our standing in the world,” the signatories wrote in a open letter on Wednesday.  “Furthermore, his expansive view of how presidential power should be wielded against his detractors poses a distinct threat to civil liberty in the United States,” said the letter, which was posted on a blog called War on the Rocks.
