Probably takes war to get South Korea out of US sphere of influence and alliance system.
The West got into east asia via war, violence and exploitation, and China was only freed from western exploitation with war. Revolution, as Mao once said, is not a dinner party/picnic. It was only the threat of violence that really got the British to leave hong kong, and to be perfectly honest, it will take violence to remove anglo power from east Asia just as it took violence to remove anglo power from Afghanistan.
China isn't just a threat to US military power, but also ideologically to the bedrock of anglo-zionist capitalism. Why was Huawei particularly targeted by Anglos? It wasn't just because of its tech and market brilliance, but also beccause its worker cooperative structure threatens the very power structure by which anglo zionists use to control companies and countries' own national champions. The success of Huawei and companies with Huawei's structure ie Chinese companies is going to put pressure on american and Atlanticist companies when trade unions in the West can look to China and demand representation and a bigger share of the profits. That's the reason why long term, the US is going to war with China, it can't afford to give up power to its own workers.
