WASHINGTON—Elbridge Colby, the Pentagon’s top policy official, wants to refocus the U.S. military on countering China. That has put him at the center of the Trump administration’s abrupt moves on providing weapons to Ukraine.
It was Colby, a 45-year-old grandson of a former Central Intelligence Agency director, who wrote a memo to Defense Secretary Pete Hegseth in early June outlining how Ukraine’s requests for U.S. weapons could further stretch already depleted Pentagon stockpiles.
