Hi @gelgoog
indonesia is barely a secular country, with islamic extremism boiled just below the surface, many muslims consider indonesia a caliphate, and nationalism is a big thing in indonesia, an american aggression will combine these two forces like jet fuel to fire
The only country that i think america might be able to "persuade" is english speaking singapore
I doubt Singapore would actively join in.
There's just too much Chinese economic and demographic influence there.
1 in 5 is a recent immigrant from China. Another 3 in 5 are of Chinese descent.
Plus if the USA and China are at war, it's going to become a racially charged war.
And the Singaporeans can't escape from their skin colour, and neither can most Americans tell the difference.
