US envoy Guilfoyle threatens regime change against any country, stoking diplomatic backlash

US Ambassador to Greece Kimberly Guilfoyle stated Washington can overthrow any government it dislikes, a rare explicit threat from a sitting envoy. The remark, reported by Geopolitical Economy Report, is unverified in mainstream outlets and likely to strain US-Greece relations and regional perceptions. It signals potential escalation in US rhetoric but may be an isolated statement rather than policy shift.
