• U.S. strikes on three Iranian nuclear sites prompt varied global responses.
• World leaders urge for immediate de-escalation and diplomacy.
• Iran warns of potential retaliation against U.S. forces and allies.

• Concerns rise over the impacts on global oil supplies amidst potential Iranian military actions.

June 22 marks a pivotal moment in international relations as the U.S. conducted strikes on three Iranian nuclear facilities, invoking a spectrum of responses from global leaders. Israeli Prime Minister Benjamin Netanyahu praised the U.S. action, declaring it a historic decision to target Iran's nuclear sites. He positioned this move as a means to prevent the "world's most dangerous regime" from developing lethal weapons, emphasizing the necessity of strong military responses in securing peace, according to Reuters and South China Morning Post.

In stark contrast, U.N. Secretary-General António Guterres expressed grave concerns regarding the U.S. military action, deeming it a dangerous escalation that threatens international peace and security. He called for urgent de-escalation and a return to diplomacy, warning that the conflict could spiral into uncontrollable violence affecting civilians, according to Anadolu Agency and Los Angeles Times.

Iran's leadership has reacted vehemently, viewing the strikes as a breach of Iran's sovereignty and an end to diplomatic efforts. Foreign Minister Abbas Araghchi stated that the U.S. crossed "a very big red line," asserting Iran's right to retaliate. He also announced his imminent trip to Moscow for coordination, indicating potential military responses, particularly through its regional allies like the Houthis in Yemen, as per reports from HuffPost and CBS News.

Countries across the globe expressed their strategic evaluations of the situation. While nations like Mexico and Venezuela condemned the strikes and called for dialogue, others like Australia and New Zealand emphasized the need for restraint and diplomatic solutions to avert further military actions in a volatile region. Their leaders reiterated the importance of stable diplomatic relations in managing the crisis, aligning with the sentiments of Channel News Asia and HuffPost.

A broader military conflict looms as Iranian military leaders have vowed that any nations supporting the U.S. strikes will be regarded as targets of retaliation. This rhetoric raises fears of regional destabilization affecting global oil supplies, particularly through the strategic Strait of Hormuz, where Iran could utilize its naval capabilities in response to U.S. actions, as reported by Los Angeles Times and HuffPost.
