Don't keep deluding yourself! I never claimed that modern planes are simpler. I actually agree that modern planes are much more complex and sophisticated than older planes. Modern planes take several decades to develop. These sophistication actually makes it simpler to pilot it as the computers & electronics will be doing most of the hard work. I am not speaking of developing time for new planes. I am only talking about training pilots which is much more easier because there is much higher quality simulators, the computers make it easy to fly and there is less need to have intense troubleshooting skills.
Huh? Then do tell me how do you program a flight computer?
It's easier to use does not translate to easier to understand, and if you have to fly plane. then you need to understand why it was use, not just able to use it, I mean, being able to figure out how AP work by tuning the Alt hold and Throttle Control does not equate to you can put the plane on a glide slope and land, you can learn how AP work by even playing Microsoft Flight Sim, that does not make you a pilot, training pilot is all about you know why or how you use those instrument. Not just what to do when you use it.
I know how to read fuel gauge does not mean I know how much fuel I need to make a journey, nor how altitude affect fuel consumption, or even how load out affect flight characteristics. This is what you need to know if you are a pilot, not just where the fuekl gauge is and what does that mean.
If flying a modern plane is that easy, they wouldn't pay 6 digits for a commercial pilot.......
As for building planes is concerned, most of the modern planes are made in modules. They already have machines and tools to build the complex electronics and other systems. These tools may take lot of time to develop but once developed, they can churn out large number of modules and parts due to automation. For eg: It takes 10 years to write 5 million lines of codes but once all codes are written, they can be copy-pasted in a minute.
So how many people you need and how much time you need to put 1000 module together? Dude, you can use the same source code, but you still need to manufacture the RAM module to hold it, even if you have the resource to produce 1000 parts, canopy, fuselage and so on, you still need people and machine to put it together.
On the other hand, how much resource you will need to produce those extra parts? Manufacturing line need service, if you expand it, you will also have to expand it service schedule
Oh, by the way, flight code is not just "copy and paste" each aircraft is built to different issue, each code are unique, even if you are coming off the same production line from the same factory and the same model, it's different because you have to be able to differentiate between 1 plane and another, otherwise if you build two plane with the same source code, your radar control, for example, will see both plane are the same, with the same squawk, same response on the transponder, and that is something you don't want when you are doing air traffic control.
So, although modern planes are extremely complex, it only affects development time. But if a plane is already developed, production can be done in a scaled manner just like how mobile phones are manufactured in billions every year. By diverting skilled employees from civilian domain, the manufacturing of defence equipments can be rapidly increased. Training of pilots and other service staff is also simpler due to availability of videos, simulators etc.
That's the most absurd comment I have seen, so building extra plane don't take time, building extra module don't take time? Training people to build and fly such module don't take time??
And WTH with mobile phone? Are you seriously comparing the manufacturing process on mobile phone with plane??
And lol, if you think training a pilot is simplier due to availability of videos and simulators, then why not just have those candidate play MFS and get them pilot license....
Do you actually know how to fly? Or you think you can fly a real plane after getting a license from Microsoft Flight Simulator??
As forWW2, USA did build 100k planes in 1944. I am not speaking of only fighter jets but overall planes including cargo or other types of planes. With diversion from civilian labour, even now, large quantity of planes can be made
I don't know where you your data from
The Second World War was the first major international conflict to utilize aerial warfare to its full potential.
www.statista.com

If you are talking about all plane, the production of all plane by the US in 1944 is 74.1K
Even the entire war, you are talking about 191,000 plane being manufactured from 1939-1945.
So either you show me some proof that US made 100,000 plane a year, I am moving on this.
As for Taiwan, it is not rich but just a vassal state of USA. It completely relies on USA for everything it has. Its dollar reserves, semiconductor are all owned by USA. Taiwan just acts as a bodyshop for cheap labour. Taiwan is too weak to be able to fight. And added is the Chinese ethnicity which makes it much harder to fight as there will be lot of Chinese sleeper agents and sympathisers everywhere. Ukraine situation is different as western Ukraine didn't have ethnic Russians. But Eastern Ukraine has ethnic Russians who readily joined Russia.
Huh? Taiwan is not rich? It's a lot richer than India......
Also, Taiwan is Chinese ethnicity also make it harder for China to quell any insurgency. If China occupy Taiwan, and Taiwan decided to raise an insurgency, that would be very bad for China. You can't catch a fish that speak your own language
As I said, if you think Taiwan don't fight, that's you, I don't have anything to talk about if you think Taiwan will just give up and let China rule.
And finally, if you are talking about Ethnic Russian (So they identify as Russian, instead of Ukrainian), more ethnic Russian are actually in the West than East, in fact, if you compare by %, Kyiv have more ethnic Russian than any city in Ukraine..........It's not hard to understand why, the more west there were, the more job opportunities there are, unless you are into farming, Eastern Ukraine does not have the same infrastructure in the west. And you can't expect every Russian living in Ukraine are into farming.
