I too have lived in Taiwan. Even despite its status as “outcast” (or because of it?) it has built a wealthy, stable and pleasant society on its own terms. The people are pleasant and their common culture binds them.
So how to defend themselves from the fascists on the other side of the Taiwan Strait? First of all do NOT count on the USA. The USA is in the process of selling out its own citizens. A tiny island far away won’t warrant 30 seconds of debate for a immoral, leftist President of the future looking for a quick deal or a headline.
Follow the Swiss. Taiwan is now moving to an all-volunteer Army. Send every soldier home with their battle rifle, 100 rounds of ammo, and a safe to put them in. Call them back every year for a day of training and updates
1 million armed citizens will make even the most bloodthirsty communist/fascist think twice.
Does Taiwan have some of our ongoing problems, like un underclass of troublemakers collecting benefits and contributing little or nothing, or an opposition party demanding communism?
