Haven't we see the tension rise up and died down many times in Past ? American planes often cross into SCS and gets warning from Chinese, I mean at this point its no brainer that nothing will happen, not that I was to see China/America fight a war but if China thinks Taiwan is their land than take it, hell even British went to war thousands of km away for Falkland Island, Taiwan is next door so what is stopping China ? Of course they are scared of world reaction and more importantly not prepared for a full scale War with America and its allies, but question is that will China ever be ? China is progressing fast and so is America, so this gap will remain between them two until one make a daring step to imitate and end this conflict once and for all, Look at Russians, their red lines were crossed and mass gathered their forces, constantly lied about any invasion and they invaded Ukraine and what did NATO do ? they are providing weapons and intel but that's it, as for Taiwan only America can interfere, no other NATO country has enough firepower to cross PLAN into their backyard except USN, now will US sacrifice their own soldiers for Taiwan ? I doubt it, and if the war happen it will be extremely unpopular among both side of political spectrum ,the Gen Z are useless attention seeking teenagers who care more about tiktok trends than actually fighting a war, that too against a military giant like China in their own backyard, yes China will lose many soldiers but their eventually win the war because once the war started, China will make sure that nothing is left for Taiwanese or Americans to defend, they will rise the entire Island to the ground and make sure that the entire country is left in ruins, not just that China will also attack USA bases in the region which in long run will hurt American interest, Imagine if a USA base in Japan is hit by China and Japanese die in the process than who's fault is that ?
In conclusion, I think the visit will go as plan and China will issue warning, maybe try to do something but not as crazy as shooting down a USA speaker, that would mean a War with US, and if that happen even those who hate democrats will join the side of pro war because those right wing who hate democrats and pelosi still are in favor of US supremacy over the world, and killing a high official of US will hurt their ego, so I think nothing going to happen same old rants/warning from both sides and we will be going back to normal by end of this week.
