As China becomes ever more assertive in the Asia Pacific and determined to protect and enhance it's sovereignty and interests in the region it seems inevitable that an attack is coming sooner rather than later on the small democracy of Taiwan.
With China having recently snubbed out democracy in Hong Kong the United States is going to have a major decision to make as to what to do when China invades the island.
Currently they don't have an official defence pact however the US continues to provide military aid and other assistance to Taiwan in what is a defacto defence arrangement if not an official one.
So the question for the west is does it have the stomach to fight a defensive conflict against China? If it doesn't it will be appeasement as another democracy falls.
This story has been written before and it didn't turn out so good.
Should the west defend democracies in the region?
I really don't see a good outcome whatever way we choose to go but it's on balance probably better having a confrontation, should they continue aggression, happen sooner rather than later.
