I think the aggressive stance of China coincides with the election of Xi Jinping in 2013, seven years ago. Trump has been in power for 3.5 years, so that's half of this time period. So it certainly _could_ be something to do with Trump.
My question was whether if would have been _such_ a failure.
It seems to me that both Trump and Xi Jinping have benefitted from the trade wars and diplomatic arguments between the countries. There seems little doubt that the Trump administration has given Xi Jinping a window of opportunity where he has been able to consolidate power and conduct aggressive foreign policy... so I genuinely wonder: how important has Trump's disastrous leadership been in the failure of this policy?
Do you not think that the second half of that period, when Trump has been president, that he may have contributed to the problem by providing an opportuniy for Xi Jinping?
I don't deny that Trump has potentially enabled Xi to make some moves faster and bolder. But those moves would likely have happened anyway and on the bright side it's maybe easier for the world to see what's going with the lies being so obvious nowadays.
