Biden doesn’t own Taiwan. (That’s a silly question, btw).
Handing over means to simply not lift a finger, and allow the Chinese to take Taiwan, with barely a fuss.
The U.S. is much weaker since Biden became president, and the military has been downgraded and not upgraded at all. We can’t fight the Chinese, unless they move beyond Taiwan and threaten us or our allies. Taiwan may be our ally, but, Biden won’t lift a finger to save Taiwan.
We have 3+ more years of Biden, but, Taiwan may be ‘gone’ before Biden is ‘ousted’ via the next election.
I don’t think we have 3+ years with Biden — he is slipping into dementia faster than anticipated.
I think China’s window of opportunity is about 1 year. Kameltoe Harris is a wildcard for them.
