My 2c:
1. Nuclear deterrent works. Unwillingness to take mass casualties in a foreign war is another weakness of America. The US is not willing to get into a direct fight with Russian due to the threat of nuclear escalation and mass casualties.
2. Because of point 1, preemptive strike on US bases doesn't make sense, it will turn public opinion and get America directly involved. Taiwan is an island, blockade and no-fly zone are sufficient to block the US from sending aid.
3. Morale of both sides is important.
a) The war needs to have a good justification to get the public on board. It is better for China to wait for provocation from Taiwan such as declaring independence, but China needs to be prepared to strike at a moment's notice. Also need to get the troops to believe in the cause.
b) From
, the living condition and morale of the Russian military seem to be really bad. If the Chinese media is to be believed PLA discipline and willingness to fight should be much better. Making self-sacrifices is a traditional value of PLA and historically it has relied on it to make up for the short falling of equipment quality.
c) Does the Taiwan army have the resolve to become something like the Ukraine army or will it be more like the Afghans. Both Ukraine and Afghans are defending their homes, yet because one is unwilling to fight the Afghan regular army didn't put up much resistance.
d) Just as there seem to be lots of Russian soldiers unwilling to use force against the civilians, PLA will probably not be willing to use arms against civilian resistance until the main fighting is over and PAP peacekeeping forces are deployed.
4) Ruaf MIA is the most perplexing. Air support has always been important and Russians are doing a bad job at it. Where are their manned jets and UAVs?
Finally, the most important thing is will both sides learn the correct lessons from Ukraine?
