In a interview aired by ABC News on Thursday, Biden was asked about the effects of the chaotic U.S. withdrawal from Afghanistan and responses in Chinese media telling Taiwan this showed Washington could not be relied on to come to its defense.
Biden replied that Taiwan, South Korea and NATO were fundamentally different situations to Afghanistan and appeared to lump Taiwan together with countries to which Washington has explicit defense commitments.
"They are ... entities we've made agreements with based on not a civil war they're having on that island or in South Korea, but on an agreement where they have a unity government that, in fact, is trying to keep bad guys from doin' bad things to them," he said.
"We have made - kept every commitment. We made a sacred commitment to Article 5 that if in fact anyone were to invade or take action against our NATO allies, we would respond. Same with Japan, same with South Korea, same with - Taiwan. It's not even comparable to talk about that."
"Plausible deniability" again on the issue of strategic ambiguity versus strategic clarity pertaining to potential US response to PRC takeover of Taiwan. This time it comes from Biden himself.
