Recently the U.S. announced that Pelosi would be visiting Taiwan. The Chinese government threatened that if that happened, they would respond militarily. Xi even told Biden the following words: "Those who play with fire will perish by it. It is hoped that the U.S. will be clear-eyed about this.". These are very strong words to be told to the president of America. But the Americans are even discussing the cancellation of the visit. Is it not damaging to the international reputation of the U.S.? Why are they letting another country to interfere with their visit to their strategic partner? Please, correct me if any of my assumptions above are wrong.
This is consistent with the policy followed by the USA since 1979, which can be summarised as "strategic ambiguity" Central to this policy is not stating the nature of the response that the US would make in the event of a military attack by the PRC on the RoC.
To this end the US is not saying "Pelosi will visit, and we will use the full range of military options available to us to ensure that this happens." Nor are they saying "We will do what Xi tells us". Instead they are remaining "strategically ambiguous".
