Earlier quoted context omitted.
1) "Last fall, the latest war game was based on a Chinese biological-weapon attack that swept through US bases and warships in the Indo-Pacific region" These are superfluous conditions (i.e. predicting bioweapons), and of course, and you're not going to hear about the 'real' results. And of course it ignores the after effects. 2) Defenders have considerable advantage in that situation, especially with a water gap. Th…
2) A giant smokescreen? Creeping (missile) barrage of the beach? There are plenty of ways to make it hard to target anything on a beach. Air cover and missile defense will be a big deal. 3) You mean the civilian population will fight to the death? Absolutely no way that's true. Russia showed the way in Crimea: offer incentives to those who support the "liberation"; it both erodes defender support and gives the attack…
Missiles barrages are not particularly useful unless they have some kind of targeting ability that we don't know about. There are not enough missiles, same for artillery. They will be able to hit communications centres and established defences, but as I said, if there is a '2 man team weapon' - and Taiwan can actually deploy them, the landings will be painful.
3) I don't agree with the Crimea Taiwan comparison.
a) 1/2 of Crimeans were pro-Russian, the rest not necessarily nationalist, or prepared. There was no material military defence of Crimea, Ukraine is poor, corrupt, and uncoordinated. Crimea is fairly sparsely populated, and nobody in the world cares about it, other than the fact it was 'taken'.
b) Taiwan is a rich, highly populated country, a strong sense of identity even if their a Pro Mainland nationalists, there are millions otherwise. They wealthy, very well prepared, very well organized. They have weapons, training a political cause. Taiwan is a mid-sized economy 'that matters'.
If CCP completely overruns Taiwan in a very heavy-handed way, with visible footprint everywhere (tanks rolling through most areas), then there might be a lack of an uprising.But if there is any coordinated attempt by Taiwan to prepare for that, and any material ability for fighters to operate, there will be ongoing fighting.
5) I think you're misunderstanding the 'reaction'.
Yes, if CCP did 'Take Taiwan' - then there's probably no way anyone would uproot them directly. Unless there was an ongoing civil uprising etc. - then it's going to belong to China.
But there would be a 1) Geopolitical re-orientation like there never has been and 2) Americans do not rollover when there is blood involved. If China 'sinks a US ship' then 'they will pay' probably a disproportionately heavy price.
'Asian NATO' will form under completely new auspices: India, Vietnam, Philippines, Japan, Korea etc. are now witnessing the China Dragon with a military conflict and so their fear escalates.
To your point about 'Neutrality' - Singapore might be, but not others, like India, Japan, Korea, and Arab countries which the US has incredible power over.
The 'South China Sea' probably becomes the forum for retribution, and I can see a multinational force, led by the US declaring that area 'open seas' and basically attacking any Chinese forces there. That'd be one way for the US to get their 'pound of flesh' to save face.
Pan Pacific Trade v2 would surely happen for the same reasons - it was going to happen, the only reason it did not was Trump, and now that he's killed it, it's just too hard to get going again. But a Taiwan invasion would trigger that. The 'possibly neutral' countries on the military side would more likely join this - their 'neutrality' is mostly based on fear of China, not fear of the West.
A Taiwan invasion might probably mean immediate trade war between the US and China, with the rest of the world dragged in.
And the more global geopolitical repercussions would be a little bit similar to the Cold War. The US/EU/UK/India/Japan/Korea+Others 'side' would put immense pressure on the system to try to isolate China.
Again, yes, I think China would end up keeping Taiwan, but it's the 'realignment' outside China that is the real impact.
Anyhow - direct invasion of Taiwan would be a big deal.
