War is never easy no matter what.

I detect a certain amount of projection in the linked article.

Deluded over the centuries by their great material superiority over the nomads, mountaineers, and jungle dwellers who lived around them, educated Chinese became convinced — and still are — that all foreigners are stupid, naïve, greedy, and easily deceived, and that all it takes to defeat them in war are clever tricks.

Hasn't the US tried to defeat Koreans, Vitnamese and Afghans? Don't some Americans think foreigners are stupid?

Pointing out that Chinese farming is not as efficient as US farming means that the Chinese only need to disrupt a small number of people and the US will starve while the US will need to affect over 425 million Chinese farmers?

If I were the Chinese, I would wait until all spare US weapons have been reduced to scrap metal in Ukraine then invade Taiwan so that worldwide chip manufacture comes under their control and everyone else's weapons systems that use electronics will be in short supply.

Taiwan Semiconductor Manufacturing Company produces an estimated 90% of the world’s super-advanced chips — indispensable components for pretty much every device you interact with day to day, like your car and your smartphone, along with a bunch that you most likely don’t, like military drones and missiles.

So, America will be low on weapons and weapons reserves. They will have limited capacity to make replacements and their food supply can be more easily disrupted. Maybe they have already started? Any food plants gone up in smoke recently? Any farmland polluted?

I hope no-one Chinese is reading this!

And then they have Sun Tzu, of course!
