The US dramatically escalated its confrontation with Venezuela on January 3, moving from sanctions and targeted strikes on alleged drug-trafficking vessels to direct military action. In a pre-dawn operation, US forces captured the Venezuelan president, Nicolás Maduro, and his wife, Cilia Flores, and removed them from the country.

The operation has prompted historical comparisons with the US invasion of Panama in late 1989. Although separated by more than three decades and unfolding in different international contexts, the two episodes reveal a continuity in how the US approaches intervention, sovereignty and legality in the western hemisphere.

The US invasion of Panama was justified at the time through a now-familiar set of claims. US officials argued they were protecting American citizens, restoring democracy following contested elections, combating drug trafficking and upholding treaty obligations linked to the Panama canal.

However, none of these arguments provided a solid legal basis for the use of force under the UN charter. Panama had not attacked the US, there was no imminent armed threat and the operation was not authorised by the UN security council. The invasion prompted international condemnation and was denounced by the UN general assembly as a violation of international law.

Yet concern over the legality of the operation mattered far less to the US than its political outcome. The Panamanian leader, Manuel Noriega, was removed from power and transferred to the US where he was tried on criminal charges. The US achieved its strategic objectives quickly and international condemnation produced no lasting consequences.

Panama thus established a powerful precedent: a smaller state could be reshaped forcibly without multilateral approval, provided the intervention was framed........
