It’s because Biden is senile and says things that are false and absurd.
He has said recently that the U.S. and Taiwan have a mutual defense treaty, which once was true but has not been true for more than 40 years (Jimmy Carter withdrew us).
He then said there is an agreement between the U.S. and the ChiComs that China won’t attack Taiwan and that Xi Jinping told him that China would abide by the agreement. This one was utter absurdity and delusion.
Now he says we have a commitment to defend Taiwan. Perhaps he meant his delusional treaty, he did not say what the commitment is.
There is no commitment.
“There is no commitment.”
Joe can send troops if he decides to. He is the President until removed.
