Because if we put nukes on Taiwan we are pulling a Cuban missle crisis with them.
Asking to be nuked.
You know we don't have nukes in Korea ir Japan right?
Yes, because they likely have nukes in the basement, and because the elites in DC are bought by the CCP, so they are not serious about giving our allies they tools they really need to deter the CCP.
Maybe Taiwan also has a nuke in the basement, but us moving nukes on to their island is more useful for also showing we recognize Taiwan as a sovereign and independent nation.
Also, since you think there is going to be a war with China anyway, why not make sure we have nuclear armed allies in the immediate region? Or do you still believe that war with the CCP over Taiwan will somehow not go nuclear anyway?
The answer to all this is...there won't be a war with China over Taiwan, because the powers in DC are owned by the CCP and the Pentagon still wants people like you to think that there is a real chance the powers in DC would ever stand up to the CCP meaningfully.
That is why we do not have nukes in Japan, SK, and Taiwan; war with China is something to be used as an excused for increased military budgets and recruitment, not something the powers in DC will actually allow to happen.
I actually would expect a war with Russia over some damn fool thing in the Balkans or Baltics, more than war with the CCP over Taiwan.
We might poke the Bear, but DC is owned by the Dragon.
