This would be a very very difficult Island to take because of the geography. Unless the nuke the entire island
Geography also play in their defense. There is a mountain range that runs down the center of the island. I would suspect that there are massive caves dug out in those mountains stockpiled with supplies.
Taiwan would not be easy to take, even with nukes.
Here’s the bottom line. You have two countries Ukraine in Taiwan that have had freedom for a couple generations or more especially Taiwan. This means the young people have been free and then somebody comes in and tries to take away their freedom their music their movies their socializing their boyfriends and girlfriends?
The girls and women in these countries will not let the men stand down. They will fight tooth and nail the same as we would.
China tries to take on Taiwan and they are going to be bloodied really bad
