How?
I know China is BIG, but so is Taiwan. The sealift power to move that many troops 135 miles across open sea would be enormous. And that is 135 miles of open sea under and umbrella of land to sea missiles the likes of which no other country as amassed.
In WWII, Okinawa was the last amphibious operation of the war; accordingly, it dwarfed all previous landings. The ground force included 183,000 combat troops drawn from the army and marines, with an additional 120,000 service troops and engineers. The transport and logistical fleet consisted of more than 1,200 ships.
Okinawa 463 sq miles. Taiwan is 13,974 sq miles.
No one is invading Taiwan without a significant build up of sea transport. That build up would be visible to anyone with a satellite. And it would take a long time to ramp up.
No…A Chinese invasion of Taiwan is not happening any time soon. It is a construct of American politicians to generate a sense of fear and urgency here.
The naval buildup is ongoing. And as others have pointed out, hostilities may not take the form of an all-out assault but rather a naval blockade.

D-Day is not necessary if one can do a blockade.
Nevertheless, the distance from the embarcation ports to Normandy is within a few km of the distance from Mainland to Taiwan.
