Does Taiwan have a Chance against China?

Depends on the style of attack.. If China launches a mass missile strike and bombing campaign the Cities and large towns of Taiwan would be smashed with huge casualties.. Much like Russia's artillery tactic in Ukraine to destroy cities but without much chance for the evacuation of the people..

The Problem for China is when it tries to launch an amphibious invasion transporting troops by ship to land them on Taiwan's coast.. China does not have enough amphibious ships to carry the number of troops needed to invade Taiwan and the Taiwanese would have the weapons needed to sink many of those ships before they reached Taiwan..

China would have to take some time destroying Taiwan by missiles and Bombers from the air to lessen the threat to their amphibious ships.. But that would give more time for other countries to send their forces to help Taiwan.. The more time for Japanese and American subs to get into position to sink the Chinese navy and prevent an amphibious invasion..

China may try to launch paratroopers to take Taiwan.. But a purely air drop invasion of a country the size of Taiwan has never been big enough to succeed.. I doubt China has enough heavy air transports available to deliver enough troops and equipment from the air anyway..

Most people just look at and compare the two opposing sides armies and come to a conclusion that China would just walk over the Taiwanese but once you understand the effect of the sea gap between the two and the huge transport capacity China would need and the huge amount of military assets needed to defend those ships trying to get to Taiwan and then the huge amount of logistics needed to keep those forces supplied then the comparisons of who has the largest army is irrelevant..

China would probably suffer huge losses and their invasion would probably fail in a great disaster for China if they tried to invade Taiwan now..
