The Lt. Gen. is slightly misreading things. China and Taiwan are not similar to the Russian Ukraine tussle, though the theme is the same type of people etc. With Taiwan, the US is policing the seas around the area. The area of Taiwan is rather small compared to Ukraine. Taiwan is a relatively rich nation and it probably already paid the protection money to the US and they already acquired sophisticated defence equipment from the US. Ukraine is a struggling nation with help required from Euros and US.USA's Grand Strategy with Russia & China. Ukraine Taiwan.

One cardinal rule: countries with Nukes and the wherewithal for second strike do not clash one on one since that would be Nuclear War.
On Nato expansion: Russia is fine with Finlad, Sweden etc. The red lines are nukes with short launch times. But that can be addressed with Russian Submarines near the US coast.
One thing that the Lt. Gen got right is that the Russia - Ukraine tussle is going to last for years.
