Yeah, and so did Obama (Iran deal ring any bells?)
That doesn't mean either deserve a peace prize. Obama continued Iraq and Afghanistan, added like 5 more or so foreign interventions, increased the drone war, waged a war on whistleblowers, etc.
Trump maintained all the wars Obama started, he almost got into a war with Iran, he's escalating tensions in Venezuela, and he increased the drone war even more than Obama did. Yeah peace prize my ass.
