As you stated there are many steps before Pelosi is in a position to "push the button." Xi today at this vary moment is practicing/simulating the murder of the people in Taiwan so he can complete his grand vision of 'unifying' 'China'.
One is using words and the other weapons. We should not tolerate such attempts to stifle an open dialog. I know it's popular now to say 'words are violence,' but at the end of the day they are still not military drills and missile launches.
Xi's posture is one of murder. Pelosi's (who I don't agree with on most things) is one of democratic freedom for the people of Taiwan.
People trying to compare the threat level of Pelosi speeches to Xi missile launches are almost unbelievable in their level of sophistry.
