Plans to send U.S. forces back into Ukraine to guard the recently reopened American Embassy in Kyiv are “underway at a relatively low level,” Gen. Mark Milley, the chairman of the Joint Chiefs of Staff, said Monday. The Wall Street Journal reported Sunday that officials are mulling plans to send special forces to Kyiv to guard the U.S. Embassy. The effort is a delicate one, as it requires balancing the safety of American diplomats while avoiding what Russia could see as an escalation. “Some of the things that may have been out there in the media, those are planning efforts that are underway at a relatively low level,” Milley told reporters at the Pentagon, seeming to refer to the Journal’s report. Such plans “have not yet made it to [Defense Secretary Lloyd Austin] or myself for that matter, for refinement of courses of action and what’s needed,” he noted. Milley added that any reintroduction of U.S. forces into Ukraine would require a presidential decision. “We’re a ways away from anything like that. We’re still developing courses of action, and none of that has been presented yet to the secretary,” he said. The Biden administration last week reopened the U.S. Embassy in Kyiv after closing it ahead of Russia’s Feb. 24 invasion of Ukraine.
