I think instead of politics, our discussion should focus on war scenarios. What is the likely war scenario and who would win and what cost?
I have had frequent battles in reddit r/taiwan recently about the possible war and who can win.
Lets's suppose Taiwan declares independence or US decides to recognize Taiwan as independent and China decides to fight. What could be the likely scenario?
Here are a few scenarios that I can think of:
1. China wants to force Taiwan to surrender but it doesn't want to do a full invasion. So, in order to reduce casualties it decides to nuke one of Taiwan's cities. I know one might bring the morality argument. But if Taiwan really goes for a "porcupine" strategy. Then why should China spend all this blood to take Taiwan when it can just nuke one of its cities and force them to surrender? It seems to be the least costly strategy both for China and for Taiwan.
A quick surrender of Taiwan is the best outcome for Taiwanese living in that island. So, I do think China might pursue this strategy if two conditions are fulfilled: the first condition is that Taiwan has alianted the mainland public so much that they no longer care about what happens to Taiwanese. They think Taiwanese are traitors that must destroyed and taught a lesson. The second condition is that China sees Taiwan takeover to be too costly in terms of manpower and damage to mainland cities.
2. China does not invade or nuke Taiwan but decides to Bomb Taiwan into submission using conventional bombs. It quickly achieves air superiority and then proceeds to create a no fly zone similar to what US did in Iraq. Then it spends the next 3-4 years to constantly monitor and bomb Taiwan from the air to soften it up. It then finally moves towards invasion with air borne troops and naval invasion.
How likely is such a scenario where China decides to bomb and blockade Taiwan to soften it up?
Both scenarios assume that US will not fight China. But lets assume US will fight China. How much resources will US spend to fight China in a Taiwan scenario and can China win in 2020-21 level of strength?
How likely is Japan's support in such a war. If Japan allows US to use its air bases to attack China for example then China will obviously not only Bomb those air bases in Japan. But could decide to punish Japan further to force them not to allow any kind of US action from Japanese soil against China. Based on my understanding of Japan. it will not want involve in this war and US will be on its own and must rely on its naval forces to fight China. Philippines, Korea and Vietnam will also stay out.
Let's look at how much strength China currently has that is relevant against a US naval force:
1200+ 4th gen Planes, 200+ Jh-7 for naval and ground strikes, 600 J-7 and J-8 which can be used for point interception roles.
50 destroyers of which 8 is type-055, 49 frigates of which 30 is type 054, 71 corvettes, 83 missiles boats, 2 carriers with 24 jets each.
12 SSN, 50 SSK submarines.
I know some of these forces are not yet fully operational but let's assume that they are for simplicity.
Ground based carrier killer missiles and anti-ship cruise missiles in vast numbers that we don't know how many there are.
US capabilities are:
1600 4th gen+ planes in the air force including 180 F-22 and around 200 F-35. But must bring these forces in an air base in Japan so likely not useful at all
600 4th gen planes on the navy used for carriers. Mostly F/A 18 hornets and super hornets. F-35 maybe in small numbers.
11 carriers, 10 LHD, 67 Bruke class destroyer, 22 cruisers, 55 SSN submarines.
Of course the quality of some US platforms could be higher than China. But I am assuming people will know the capabilities of such platforms.
I am not counting ground forces for US because I don't think they are a factor in the US-China battle for Taiwan. I think its mainly a Air-naval battle for Air superiority. Navy is mainly a platform to fight air attack- air defense battle. Submarines are a support force for sinking ships.
I can envision two scenarios about how much forces and how much cost US is willing to take:
Scenario 1: Arrogant US. This is the scenario where US is arrogant that Chinese forces are weak. And there is not much willingness in US public to fight a costly battle for Taiwan. US will fight China but does not want to give up on its global empire.
Suppose they send 3 carrier battle groups and associated ships to fight China. They assume China will intimidated by just the thought of fighting US. But if not then 3 battle groups will be sufficient to achieve air superiority over Taiwan strait and thus defeating China.
Scenario 2: China threat crazy US. In this scenario, US is totally paranoid about China. It cares about nothing but China. Anything that can cause a gain for China will resisted by US with force. It has abandoned its empire in Europe and Middle east. And decides to use its entire navy on China.
It will send its entire fleet of carriers. Due to maintenance, it can bring about 8 according to navy scheduling. So, 8 carrier battle groups and associated destroyers and cruisers and SSN.
Can China win? How many carriers can China sink with its Carrier killer and anti-Ship missiles? Can China simultaneously battle to invade Taiwan as well?
Here is what I think: I think US underestimates China heavily and especially discounts China's organizational capabilities and tactical accumen. My analysis is that China is invincible in the first island Chain based on the capabilties it has right now. China can use its entire air force and ground based missiles in this fight. China's 600 Flankers give them very long range capability. US carriers can be attacked by China from about 1000 KM easily with H-6K bombers with missiles and 600 Flankers and 200 Jh-7 can also carry anti-ship missiles. China's destroyers will also fire their own anti-ship missiles in a massive barrage.
Thus China will be able to track those carriers using its satellite, drones, recon planes and subs. Once they get nearby, they will be destroyed with saturated anti-Ship missiles.
What are your thoughts about these scenarios.
