Which firm and from which of those countries are going to build it? India? What's their expertise on HSR? America? They can't even finish the mearsed line on time and within budget, Saudi Arabia? By hiring China Railway Corporation to do the work sure. Who's going to finance this fantastical plan, U.S. Fed printing of $$$ that's going to go nicely with their already sky high interest rate for their debt.
I don't think so, but the possibility of violence is not improbable if Bong Marcos Jr. ignorantly assumes he can escape the Philippines unscathed to be with his family along with his deceased father's embezzled money parked in the U.S. and Swiss banks. Not to mention that the Philippines is actually not that enamored with the idea of going to war with China due to the decentralization of news from the help and proliferation of smartphones and social media like Tiktok, Facebook etc. Plus, Duterte the former president still has some sway within the Philippine political landscape.

Because the US has more or less defaulted on its debt by taking interest from US treasuries owed to Japan and reinvesting it back into US treasuries, whilst allowing the quid pro quo of providing political cover for Japan dumping Fukushima nuclear contaminated water. Japan had apparently wanted to use that US interest to save its currency but the Anglos are facing down dedollarisation.
