New Pentagon chief Mark Esper’s mission: confront ‘growing threats’ from China, manage impulsive Trump
- Mark Esper’s confirmation adds some stability to Trump’s national security team after a long vacancy
- He will also be steering US defence strategy as it shifts to confront China and Russia as the department’s main challenges

Former soldier Mark Esper was sworn in as US secretary of defence Tuesday after earning Senate confirmation, filling America’s longest-ever Pentagon leadership vacuum as it faces mounting tensions with Iran while locked in strategic competition with China.
US President Donald Trump’s second Defence Department chief takes over nearly seven months after the shock departure of James Mattis, the deeply respected career US Marine who broke with Trump over policy on the Middle East and Afghanistan.
Esper sailed through the confirmation process at lightning speed. He earned broad bipartisan support and was confirmed by a vote of 90 to 8.
Later Tuesday, he was sworn in at an Oval Office ceremony attended by several Senate Republicans and Trump, who called it “a very important day” for the nation.
“There is no one more qualified to lead the Department of Defence,” the president said.
Esper steps into the top Pentagon job with a long list of crises on his plate.
