What you said about them siding with China against a common aggressor makes sense. In fact they already did this against the Japanese and took a pause from their onw conflict to fight the Japanese together during WW2.
And it's also true that this "China aggression" is pure Western propaganda.
Which country has been bombing and waging a war somewhere since the inauguration. The same country that has over 700 military bases over the world. (China has 0)
"...rocket's red glare, the bombs bursting in air.."
Who’s been invading and bombing other nations so far lol.
