lol well if you knew your history you would know they tried and failed. The PLA lost at the battle of Guningtou which effectively halted their advance towards Taiwan. Then the Korean War started and completely changed their priorities for years to come. Ever since then it’s been a back and forth arms race of Taiwan’s ROC maintaining a sufficient military readiness up to around 1980 as to deter China from taking action. Then the US got heavily involved and Taiwan became a center for semi conductor manufacture. It became a critical partner for countries around the world because of this and this bolstered the ROC’s access to advanced western military equipment and help from nations dependent on Taiwanese industry also China itself became a major trade partner with Taiwan(bizarre right?). But the new CCP and PLA leadership of today are not like their counterparts of the past. Pooh Bear is a true despot who really wants the one China dream and cares little for the people. He has expressed real interest in aggression regardless of cost and needs a distraction to economic woes. Much like his Slavic counterpart’s dream of reuniting the USSR pooh also has the One China bug hence actions taken in Hong Kong. He would have been all to happy to conduct and all out invasion and there was real evidence he planned to do so; However, the Ukrainian response I believe took them by surprise and Taiwan is much better prepared to repel an attack than Ukraine was.
