Show me an instance in history in which a rising power soft-powered itself past an incumbent waning power?
Soft power as an analytical overlay or categorical perception does exists but it exists predicated upon the underlining hard power... in and of itself in a vacuum is useless... Yes, China is comparatively weak at soft power and has room to grow, but in the end the difference that makes a difference will be in hard power... nukes, technology, military, etc etc
Could soft power have saved the Native American's fate? What about the Qing dynasty against the English during the Opium era?
Having soft power will benefit China but look at India... In the end, soft power is a lagging indicator and chases the tail of hard power... its not going to be a deciding factor in the grand scheme of things in terms of how the China Century turns out... if China wins, soft power will naturally follow up eventually....
This is the difference between a poor guy working on his "game" to try and score hot girls and a guy that works on his fundamentals in terms of getting fit, earning more money, developing himself in terms of skillset, pesonality, habit, lifestyle, rather than focus only on cheap parlor tricks and "game" to get women...
Because at the end of the day soft power serves hegemony, not the other way around, just like 'friendship' is a tool of hegemony, and hegemony cannot be bent by 'making friends'.. Recall everyone bought the WMD lie that US used to attack Saddam for Iraq going off the petrodollar. If it wasn't WMD it would be another excuse... doesn't matter... then they use the same lie to say Iran must be sanctioned... then they use the fact that they sanctioned Iran illegally and based on a fraud/lie to kidnap Huawei CFO. Then they use the lie that Huawei broke US sanctions to blacklist Huawei and put Huawei on entity list... Then they don't even bother anymore with even the semblance of an excuse and now directly sanction SMIC because "China Bad"... what you don't understand is that the decision was predetermined, and they work backwards for the excuse... soft-power means nothing here... in this case no amount of softpower was ever going to change the outcome, which was always predetermined by the US....
