1. US national security relies on Taiwan/TSMC being free from Chinese control. Strategic policy, training, and military funding factors this into how we would respond to a Chinese invasion. This is GUARUNTEE. this isn’t an opinion. This isn’t a maybe.
Chinese push reunification ideology, but they don’t have the military power to make it happen. It is a scenario that they know they cannot currently win. China knows it. US intelligence knows that China knows this. This is a fact understood by all sides. Of course China doesn’t include this fact in the indoctrination of their citizens. There’s not much else to discuss on this.
2. The NVA suffered casualties massively higher than US and South Vietnamese combined. Please do more research on the war before making statements.
I didn't say NVA suffer lower casualty, I'm saying you shouldn't omitted the sacrifice of South Vietnamese just to make US more badass, If US didn't get South Vietnamese help their casualties will be higher. Also many of that NVA casualties also the result of overwhelming US air superiority.
Korean War: the US pushed north Korea back to the 38th parallel. China and Korea couldn't hold the ground they took over even though the US is a ocean away and they are directly next to the land the war was fought on.
Vietnam war,: the US absolutely decimated the NVA from across an ocean. 70k US deaths vs 1 million+ NVA deaths. Again, in a war we fought an ocean away while they were next door. The Vietnam War was lost due to politics not capability. It was a decision to leave vs. Not being able to keep up.
Afghanistan: again. Another war thousands of miles away where we decimated the Talibans control of their own territory. The taliban was great at small scale ambushes and IED's but the death toll we suffered was a few thousand over 20 years. Can you guess what their death toll was? We established bases with air-conditioning and fast food restaurants etc. They had no ability to expell us or prevent us from maintaining control of territory. Another political loss vs. Being run off the battlefield.
One big difference that war with China will have compared to these previous war is China has the means to strike US bases in the regions. China didn't have the means to attack US bases in Japan during Korean War, Vietnam didn't have the means to attack US bases in Thailand and Philippines during Vietnam War, Saddam didn't have the means to attack US bases in Saudi and Kuwait during Iraq war, Taliban didn't have the means to attack US bases in Pakistan and Uzbekistan during Afghan War. China has the largest constellation of spy satellites after US and they have thousands of ballistic missiles at their disposals that could reach as far as Guam. If they spot US stockpiling weapons and supplies in Japan, Korea, or Philippines that could be used against them do you think they won't preemptively strike it? if they spot US ships refueling and rearming in shipyards in Japan, Korea, or Philippines do you think the won't strike it? China has more resources at their disposal than any of previous US adversaries, and looking at the current events in Ukraine and Israel, keeping US busy by destabilizing their allies across the world is a good strategy. Let's say China decided to give weapons to Russia, Iran, North Korea, and every terror groups with axe to grinds against US, does US have the resources to deal with all of them at the same time?
