From a Foreign Affairs press release:

Massachusetts Institute of Technology Professor Barry R. Posen argues that despite fears that Trump would prove to be an isolationist, in practice, he has been anything but. “Across the portfolio of hard power, the Trump administration’s policies seem, if anything, more ambitious than those of Barack Obama,” Posen writes. But Trump has deviated from traditional grand strategy: “He still seeks to retain the United States’ superior economic and military capability and role as security arbiter for most regions of the world, but he has chosen to forgo the export of democracy and abstain from many multilateral trade agreements. In other words, Trump has ushered in an entirely new U.S. grand strategy: illiberal hegemony.”
