In 2016, I signed two high-profile public letters, in which senior national security professionals from various Republican administrations declared their opposition to a Donald Trump presidency (see here and here). I also organized a third anti-Trump letter signed by the country’s leading specialists in civil-military relations. I do not regret signing those letters. Trump’s destructive performance in office has entirely validated the concerns they raised.
There is now a similar letter endorsing former Vice President Joe Biden for president, signed by some 70 former Republican colleagues, many from the ranks of the 2016 signatories. Once again, I agree with its most important fundamental claim: It is not in the U.S. national interest for Trump to be given a second term. It is time for the country to move on.
