Want to see shit really hit the fan? Imagine if Taiwan applied for NATO membership. They are already recognized by most countries as an independent entity and I assume are aligned with many Western goals since they conduct joint military exercises with the US, but China would go crazy over attempts at NATO membership.
Makes me wonder if there are are any rules to prevent acceptance if a country is attacked because of asking to join? Like I know Ukraine can't join right now because they're already at war (despite whatever Russia wants to call it), but I think Taiwan is not officially at war with anyone.
