The government has plans for if the Girl Scout try to take over the US; never going to happen, yet someone still gamed it out.
I'm not happy with the loss of trust in our gov with regards to this, but before now the CCP didn't have an agent in the Oval Office, or could make the Mouse bow to them.
Our allies may be pissed, however I want to point out that to the person on the street, and to the people who are in Beijing's pocket already, risking war with China over Taiwan may not seem worth it. Not with the risk of nuclear escalation and MAD a very real possibility if we go to war with China over Taiwan.
I do not think many Americans are willing to risk our homeland and civie population for the sake of Taiwan, regardless of the consequences of breaking our defense pact.
