I do agree that the disparity is large but taking more lessons from Isreal and HAMAS in my opinion is the wrong choice given that Taiwan would fight at first more like Ukraine than HAMAS, HAMAS has no modern weapons they attack and then hide and repeat but Taiwan wouldn’t do that until later on. At first Taiwan would be using their tanks, missiles, artillery, and any remaining fighters to attack China and using their ground troops to hold ground and counter attack what none of that HAMAS really does but now once those things are mostly destroyed and they are running low on troops now they woukd start to fight like HAMAS more but taking more lessons from HAMAS and isreal because of the disparity between the two is similar in scale to Taiwan and China doesn’t account for the weapons and way taiwan would fight at first what is why I think China should take more lessons from Russia and Ukraine.
Well it's not about "modern" systems or not. The IDF needed to neutralize Hamas as a fighting force, because that's really what it's about.
The specifics are also quite similar as well. Gaza is an urban jungle with extensive underground fortifications. The entire area is almost like one giant bunker with mazes built into it. The IDF's challenge was having persistent ISR to shut down pop-up threats from Hamas's rockets and counter-attacks which could pop up essentially anywhere in Gaza.
This is very similar to the challenge PLA will be facing in Taiwan. On top of that, unlike the IDF, Taiwan is full of people and areas that PRC does not want to destroy or kill. Gaza is still useful here because it's really, the perfect example of how challenging it is to manage large masses of hostile people, while trying to kill fighters and war material hiding amongst them. Which will almost certainly be the case in any Taiwan scenario.
Now the reason I want to shy away from Ukraine and Iran is because the challenge there is completely different. Both Iran and Ukraine are far too large to have persistent ISR on 24/7. They're also far more sophisticated and have far greater magazine depth than Hamas. The mission therefore, for both Russia and IDF, is less about 24/7 ISR and Scud hunting, then it is about air defense.
I.E. in the Iran and Ukraine case, the IDF and Russia have to worry about hardening their critical nodes and attriting misisle volleys, as well as finding ways to paralyze the enemy's ability to fight. It's much close to "peer-conflict".
Whereas in a Gaza or Taiwan scenario you're not fighting a peer. You're really, managing an insurgency within a far smaller geographic area.
Yes, I take your point that Taiwan is, likely, much more capable than Hamas, but China is also much more capable than IDF. The assymetries between the two belligerents are just too big. It's a different kind of war.
