You have probably never heard of Dan Caldwell. But he is playing a major role in shaping President Donald Trump’s foreign policy. As head of the transition’s “landing team” at the Department of Defense, he is stocking the Pentagon’s all-important middle ranks with policy personnel who share his view that the U.S. needs to dramatically reduce its military footprint abroad, according to four Trump administration officials who spoke to The Free Press of Caldwell’s mounting influence with concern bordering on alarm.

And Caldwell is going places. Two Trump officials told The Free Press he is slated to become deputy to retired general Keith Kellogg as Trump’s envoy to Russia and Ukraine—which would give him extraordinary influence over the peace negotiations between the two warring countries.

If the “restrainers” have an intellectual leader it is Trump’s choice for the number three position at the Pentagon, Elbridge Colby. The grandson of William Colby, the legendary CIA director, Bridge, as he is known, has written eloquently about the danger an overextended military poses to America’s ability to deter China. He makes a compelling argument that America’s involvement in Ukraine and the Middle East saps precious resources from a future conflict with China.
