Maybe we should stop selecting islands next to China to be global critical supply chain hubs. I mean, even if the Chinese were non-expansionist and benevolent, it's still kind of tempting them a little too much.
Maybe its time for people to stop being paralyzed by fear and invest in their future. If China is such a severe threat to Japan, then invest more in the JSDF. Yes, China is powerful and has an aggressive stance, but that's no reason to give up without a fight. Japan and South Korea together can very nearly match China's shipbuilding tonnage per year, and besides that Japan collaborates with America to develop advanced naval missiles like the SM-3 Block IIA. Effective deterrence of China w.r.t. Japan should be achievable if people stop overdosing on blackpills.
But yes, I agree Japan, Indonesia (as was intended), etc should wise up.
Your "whole humanity 'We'" isn't who's investing in chip industry in Hokkaido. It's Japan.
Same time, Japan clearly wants freedom to do things its own way. Good. It has the freedom. It just has to take it. Do it.
And that's just one part of the expansion. But the short version is that the JSDF isn't staying a defensive only institution.
The other side of this is that modern large military ships are almost literally unsinkable. It is very difficult to get enough explosive on target due to their extreme damage resistance.
When the military does live fire exercises where they attack obsolete military vessels with no active defenses using torpedos, missiles, bombs, etc, they usually don’t manage to sink it. They have to send a specialized demolition crew afterward to actually scuttle the damaged ship and turn it into an artificial reef.
An operational large military vessel will have layers of substantial active defenses that make this even more difficult.
The whole point of the navy is to be able to control waterways. The whole point of being able to control waterways is to be able to economically ship large amounts of material and people; in the case of warfare, soldiers, bullets, food, water, fuel, etc.
An unmanned fast attack sub is going to be useless for defending your logistics fleet from strike fighters and anti ship missles. Even a dingy that has a guy in it with a rocket propelled grenade can send a cargo ship to it's grave. You have to have a surface ships with powerful defenses to protect them.
Being deeply embedded in global supply chains and your allies’ economies makes it a lot more difficult for them to justify abandoning you to your enemies.
Shouldn't you take WWII history into the account?
1. South Korea - Korean war happened and majority of South Korean want US military base there 'cause you know North Korea with its nukes point at Seoul.
2. Japan - well, everyone know what happened and the treaty were signed thus military base in Japan.
