Number 14 in the United States and Philippines Bilateral Defense Guidelines, forged on May 3 during the official visit of President Ferdinand Marcos Jr. to Washington D.C, states, “An armed attack in the Pacific, to include anywhere in the South China Sea, on either Philippine or U.S. armed forces – which includes both nations’ Coast Guards – aircraft, or public vessels, would invoke mutual defense commitments under Article IV and Article V of the MDT.”
The first paragraph under Article IV of the 1951 U.S.-Philippines Mutual Defense Treaty states, “Each Party recognizes that an armed attack in the Pacific area on either of the Parties would be dangerous to its own peace and safety and declares that it would act to meet the common dangers in accordance with its constitutional processes.”
Article V states that “for the purpose of Article IV, an armed attack on either of the Parties is deemed to include an armed attack on the metropolitan territory of either of the Parties, or on the island territories under its jurisdiction in the Pacific Ocean, its armed forces, public vessels or aircraft in the Pacific.”
With these commitments, can the United States invoke the 1951 U.S.-Philippines Mutual Defense Treaty to be allowed to use the EDCA sites in Cagayan, just about 600 kilometers to Taiwan, to launch attacks to stop the Chinese from taking over Taiwan?
