There is absolutely no point in starting a campaign against China. We need them as an ally not as a foe as we might need military support one day. The USA with Trump in charge in attacking every country he doesnt like. So when the US courts award Trump $5 billion libel damages against the BBC and we won’t (rightly) pay we might be vulnerable.
Iran can fight back from this illegal and unprovoked war because China supports them. The USA cannot defeat China.
