Kerry, I understand your concerns and empathize with them per America getting sucked into a wider Middle East war. However, as a strategic communications professional who’s worked in the White House and Congress, I would note that what is said privately and publicly between government leaders can be completely opposite. This is to say that Biden may have tried privately to convince Netanyahu not to invade Gaza. We just don’t know. What I do know is that Israel will do whatever it takes militarily to safeguard its national security, sovereignty and existence—regardless of what the USA or anyone else says or does to the contrary.
Moreover, I know that America does indeed have a moral and foreign policy commitment and obligation to Israel dating back many decades to 1948. Additionally, the pro-Israel lobby is so strong in its influence over Congress that I don’t think America will break from its current position of fully supporting Israel—at least not in the foreseeable future.
Despite your strong points, I believe that comparing the situation to Neville Chamberlain’s capitulation is unwarranted. That’s because the two situations are very different, like comparing apples to oranges. Thanks for considering these points.
