If there's a war, China will only attack Metro Manila (sadly which affect me) and see this gov't collapse immediately as you see Marcos going to Hawaii ASAP (where will he go, to Vigan Ilocos Sur? his hometown is in the frontline).Philippines is nothing like Ukraine.
Philippines is divided into dozens of ethnic groups, with a decades long insurgency by Muslims in the south against the Philippine government who also fought against Japan and the US before them. What's US going to say to Muslims about Philippines?
Philippine military is far more corrupt and incompetent than Ukraine's, Philippines is literally named after a foreign King of Spain and was created by the west.
