Hmm,if I were Taiwan’s president & had nukes,why would I put several of my best pilots at risk to nuke something a 1000 miles away when there are several Chinese military installations close by??Since you brought up nukes,why bother about the 3 gorges??
All available sources seem to suggest Taiwan doesn’t have nukes or atleast hasn’t restarted what papa Bush nudged them to stop.
Hit your enemies where they are weakest and where your strikes will do the most damage.
Kill 10,000 people on a hardened military base ... big deal to the average Chinese man.
Kill 3 million plus with floods from a dam busting? Yeah, the chinese are going to think twice.
