On April 2, 2022, Task Force Powers left the Port of Tumi. Task Force Powers was made up of four destroyers of the Miele Navy. Task Force Powers was given orders to intercept any Galloian Navy vessels, and escort them out of Miele's waters. If the Galloian naval vessels refused to leave, the Task Force was authorized to use all force necessary to expel the Galloian naval ships. On April 4, 2021, Task Force Powers encountered the Galloian Frigates Bigglesworth and Farbissina about 100 nm off the coast of Miele. The Galloian frigates were escorting several fishing vessels. Task Force Powers issued a warning to the Bigglesworth and Farbissina to leave Miele's waters immediately. When the Bigglesworth and Farbissina refused, the Miele destroyer Austin opened fire. After a battle lasting nearly an hour, the Galloian Frigate Bigglesworth was sunk. The 89 surviving crew members were captured by Task Force Powers. The Galloian Frigate Farbissina retreated to Galloian waters. On April 5, 2020, Miele's Ambassador to the United Nations delivered a letter to the Secretary-General advising that the actions of Task Force Powers had been taken in self-defence, and invoked Article 51 of the UN Charter. On April 6, 2022, President LaPier of Quercus made a statement denouncing "Gallo's unlawful aggression and imperialist attitudes". President LaPier added that "Gallo's ability to wage aggression against Miele must be curtailed". In the early morning hours of April 7, 2021, Quercus' military launched a series of cruise missile strikes against Galloian navy targets, including the port where the Galloian Frigates Bigglesworth and Farbissina were based. The daylight raid resulted in significant casualties (some 200 dead and three Galloian navy vessels sunk). At an emergency meeting of the UN Security Council on April 10, 2022, Quercus' Ambassador to the UN stated "Quercus' actions were undertaken in solidarity with the Kingdom of Miele in response to the multiple incidents of armed force undertaken by Gallo against Miele, and in conformity with the right of collective self-defence." The Kingdom's Ambassador to the UN, speaking at the same meeting, expressed thanks to the Republic, stating that "while Miele had not felt the time was right to respond to Gallo's aggression, and had not discussed the matter with the Republic, the Republic's missile attack sent a clear message that armed attacks by Gallo would not stand."

You are a legal advisor to the UN Secretary General. You have been asked to provide a legal assessment with respect to the April 7, 2022 missile strike by Quercus against Gallo. Provide an analysis of the legal issues that arise, and an assessment of the lawfulness of the conduct.
