My candid opinion (if anyone cares)...
China feared Trump could release a dreadnought if he were able to unite America. Had Trump actually put America First (which he claimed), then ultimately US would've been a serious threat to the Communist regime. This gave them (CCP) the reason to divide and conquer, and Democrats were a duped asset. The two-party system worked in their favour. Covid was the result - no nukes or any amount to force could stop. In retrospect, nobody can really lay all the blame on Donald for the current situation, except the denial of science. Unfortunately, he is the master of his own ego, and divisive politics the downfall. IMO.
