Ex-president Trump escalated Obama's drone wars and made them more secretive:
"The Trump administration has carried out 176 strikes in Yemen in just two years, compared with 154 there during all eight years of Obama’s tenure..."
"Trump has peeled back all of those requirements because, well, he can. We now know more than we did about U.S. drone wars when Obama first took office, but less than when he left."
Under Donald Trump, drone strikes far exceed Obama's numbers
He used a modern bomb for the first time:
"Fourteen years after it was deemed ready to use, the U.S. unleashed the moab for the first time in combat on Thursday, at 7:32 p.m., against an isis affiliate in Afghanistan’s eastern Nangarhar Province, along the border with Pakistan."

He also expanded US nuclear weapons:
"In his single term in the White House, Donald Trump expanded America’s nuclear arsenal and undermined decades of arms-control efforts."

Suggesting the former President "never started any wars" as if he was a peaceful President is misleading propaganda.
