Taiwan is nothing like Ukraine. It's a civil war, and realistically only the risk of open warfare against US kept reunification from happening in the past 70 year.
Do you know how Ukraine managed to turn things around when it was badly losing in May? HIMARS, with NATO providing target intelligence. Russia supply depots were systematically targeted, which devasted Russian logistics. As a result, their artillery units could no longer provide the high volume of fire needed to support their advances. Except in this case, China would be the one whacking Taiwan with superior precision long range artillery and battlefield intelligence.
Unless Americunts decide to directly intervene, Taiwan is a done deal. The day China can defeat US in open air and naval battles in Western Pacific is the day unification begins. I'm thinking 2035.
First of all, Ukraine did NOT turn things around in May, it was a failure from Russia from day 1. They did not have any significant gain since they took Kherson back on 3rd March, Mariupol should fall within days and the very fact that they are able to hold out for 83 days is the very reason why Russia systematic failed in Ukraine. Because since Probably Day 13 when they reach the outskirt of Kyiv (Irpin, Bucha and from the other side on Brovary) because that is the high-water mark of Russian gain, since then Russia has been losing ground constantly. Yes, they have successful battlefield gain, but they are small and tactical (or otherwise local) and it was dwarfed by the Ukrainian gain over the period.
HIMARS played a role, but like TB-2, it is NOT a decisive role. Bear in mind Ukrainian gain were mostly come from maneuver warfare, not siege warfare, artillery support does not give them the edge, it's battlefield mobility, command and control are the key for Ukrainian success, it mean it won't matter for in Kharkiv if they have no HIMARS, and the fact is HIMARS, and other artillery piece were not heavily used in the North.
On the other hand, same cannot applies to Taiwan, because there is one thing you know what to hit, another thing is would you be able to hit them. Just like ground bombardment from the start of the Ukraine war, you would most likely able to take out part of Taiwanese defence, but any good army would have duplicate C4I structure, either airborne or underground or both, those you can't hit, which mean if you are betting on a complete artillery/missile strike will paralyse Taiwanese defence, you simply won't. On the other hand, unlike in Ukraine, where you have a land border, you now have a sea between Taiwan and China, where one side of Taiwan facing an open ocean, it's next to impossible to blockade Taiwan unless you want to do what Russia do by parking their ship outside Taiwanese harbor. And if Ukraine which have next to zero Anti-Ship capability can sink 7 Russian ship, now imagine what Taiwanese can do with proper anti-ship and anti-air technology.
And the sea would act as a very nature blocking position, because you can only allow some of your troop to land, and it make sure your logistic challenge is maximum because you do not have sure fire way to carry supplies and maintain the log train except for using ship, ship can bring in a lot of supplies in one go, but the down side is you need a port to support that on both side, then come the question, would you take down Taiwanese port and its defences? Because if you do, you will not be able to supply your troop using said port, which hamper your pace of operation, if you don't you will be facing a stiff defence trying to take the port. I am pretty sure the 3rd option, which is Taiwan are willing to surrender the port to you is almost out of the equation.
And then you talk about Battlespace intelligence, first of all, it's naive to think the American will not supply any to Taiwan even if US choose not to engage like they did with Ukraine. US intelligence are probably the most comprehensive in the world, which mean they can be relaying intelligence to Taiwanese first time on almost the entire Chinese coast as things happen, and seeing there is a sea border between the two, there are lag time what you can do in China toward Taiwan, simply because whatever you do will need to transit the Taiwan strait, which give Taiwanese advance warning to prepare for such a move. And you can't touch those US intelligence unless you want a war with the US.
If you combine all these factors, and if you know anything about military operation, you will know this is not a cake walk. Just calling name and cussing "Americunt" will not change the fact that even America is not involved, a smart enemy will make this a tough fight.
Again, I don't expect you to understand what I said, because you weren't a trained soldier nor have you planned any operation before, all you have is what you think when everything goes your way, when you are a military planner, you can't see things all rainbow and rosy. But then seeing what you wrote, you probably do not understand this concept. And I ain't even try to go into technical term.
