"HR McMaster has resigned as Donald Trump’s national security adviser and will be replaced by John Bolton, the hawkish former US ambassador to the United Nations, the president announced on Thursday night.
"Bolton has advocated using military force against Iran and North Korea and has taken a hard line against Russia.
Trump announced the switch in a tweet, writing that he was “thankful for the s"ervice of General HR McMaster who has done an outstanding job & will remain my friend”.
"The changing of the guard will take place on 9 April, Trump said.
"An official said that there were no incidents that led to McMaster’s exit, and that it was instead the result of a continuing conversation between McMaster and the president.
"In a statement, McMaster, 55, said he would be retiring from the US army at the same time as leaving the White House. He thanked Trump and the members of the National Security Council, who he said had “worked together to provide the president with the best options to protect and advance our national interests”.
"His replacement, Bolton, 69, who has long been a polarizing figure in Washington foreign policy circles, becomes Trump’s third national security adviser in 14 months.
"The departure of McMaster had been on the cards for some weeks amid ructions with the president. The pair have clashed several times over policy issues such as Afghanistan and Iran." . . .
