Biden reminds me of the dad that helps out his son. When he refuses to give his son money for an investment he feels is bad his son then turns on him like a rabid dog.
C'mon man!
I believe I'm on the record supporting Biden's actions many times when others were critical. But the weapons embargo is a horrible position for the administration. And not so much because I think he must deliver the weapons; but rather, it's the PR of it that I have issue with.
If this would've been done in private, and kept under wraps, then I would have no issue with it. The US certainly may try to pressure Israel vis-à-vis a weapons embargo to act with the US interest in mind if they rely on US support.
However, if the secrecy of such embargo can't be guaranteed, besides being futile, the repercussions could potentially be many times worse. That's what I have issue with and why I think this was a very serious strategic mistake. In fact, I believe that it is such a strategic error that I have serious concern the president was not consulted with or was ignored on this decision.
Using your 'dad investment' analogy, this is more akin to Warren Buffet, in an effort to 'save' his son from making a strategic misstep in his public company publicly announces that he'll halt a sizeable portion of a planned cash infusion. Do you think that move would save said company?
