Remember - Harris was a VICE president. VICE presidents do not have a life of their own, nor, I suspect, a thought of their own. They are there for one purpose - back the president and stand in if necessary. That being the case, and being aware that she is a vice president she could not do that as it would be going off away from her president. The while Kamala Harris thing has given me some humor. Vice presidents actually do very little and ITS ALWAYS at the behest of the president.
All that being said I fear that Biden should never have stuck with Netanyahoo. That man is a monster and a charged criminal by his own government. Apparently the only reason he is not in prison is because he continues to hold his position. Biden dragged her right down that path. There were thoughts expressed (few and far between). Anyway, I think you are probably right. That deal is a serious mess and we were right in middle of it.
