Capture of Taiwan in a few days??
last time I checked, Taiwan has 100K men on arms + many more on reserve, their army's only mission is to defend against China, Can China airlift or sealift 300K men + tanks + equipment? I doubt it
China can't invade, China can launch missiles, but that alone won't defeat Taiwan, unless they are nuclear armed, but then they would face nuclear retaliation
The battle, IMHO, would be resolved in about 5 to 7 days, yes. China would be able to do this with air supremacy over Taiwan due to the proximity of Chinese airbases and the S400 and S300 weapon systems. Taiwan's AFs would be pockmarked with Chinese SSMs and any attempt by Japan or the US to come to the aid via the air would be met with massive Chinese CAP and SAMS.
No one believed the US would destroy Iraq's army in 100 hours so think about that.
1st, because of logistics involved, you can't hide this kind of operations; satellite will pick any strange movement in mainland China. Taiwan will call reserves as soon as they assess Chinese intent. So now you have ~1 million men in arms, in well defended, fortified bases, with plenty anti ship and AA missiles
SSMs showering over Taiwan most likely trigger a US response. A US plane shot by a SAM will definitively
Enter the USN and China simply can't move troop ships on the strait
Even without the USN, Taiwan's navy has enough capabilities to pose a risk to any invading force, would China risk their few capable amphibious ships?
SSMs might degrade, but not eliminate Taiwan's capabilities as most of their AFs are hardened
Even if it succeed in destroying their air force and navy, you still have the army. Was Israel capable of totally destroying Hamas/ Hezbollah, etc with air attacks?
Without US support, it would take at least a few months to conquer it
With US support, the Chinese don't have a chance
