US House Speaker Nancy Pelosi is expected to visit Taiwan as part of her tour of Asia, according to a senior Taiwanese government official and a US official, despite warnings from Biden administration officials, who are worried about China's response to such a high-profile visit.
The USA has officially recognized the One China Policy since Nixon. There hasn't been any official diplomatic contact with or visit of an American head of state in Taiwan for more than 40 years. That's the reason why the Chinese government emphasizes so much that Pelosi is the third highest ranking person in the US government, her visit would be seen as the US government once again officially recognizing Taiwan as an actual country, which would break existing treaties between the USA and the PRC.
I'm not saying they'll invade Taiwan in return or kick off WW3, but something substantial will happen.
Newt went in 96 and China threatened nuclear attacks and military invasion of Taiwan. So it's been 25 years
