Unyielding tackles a recurring topic of national importance as a history lesson for future generations. Controversial illegal medical mandates impacted military populations for many decades, but it was not until the COVID-era that the American people witnessed similar overreach.   Colonel Tom “Buzz” Rempfer’s memoir retraces the anthrax vaccine history since it marked the first time the military was served with court rulings condemning premeditated illegal experimentation on our nation’s troops. The advent of COVID mandates, imposed on the population in 2021, gave the American people a taste of the mistreatment previously reserved for our nation’s warriors. Legal protections enacted by the Congress to guard against medical experimentation, meant to ensure safe, effective, and FDA-approved products, were instead adulterated to foist mandates on American society.   According to the FBI, the motive for the anthrax letter lab leaks in 2001 was to “rejuvenate” the “failing” anthrax vaccine. Similarly, the suspected Wuhan lab leak two decades later resulted in a push for COVID injections. The pattern of fear-based bioincidents resulting from reckless biodefense enterprises, and lessons not learned with illegal mandates, paralyzed government and military leaders while wreaking havoc on the trust and health of our troops and the American people.   Buzz’s decades-long analysis of the breakdowns stands as a unique treatise on the failures of leaders to learn lessons from these enduring clashes and to correct the damage. Future generations will sort out the aftermath, but in the meantime, Colonel Rempfer’s Unyielding effort attempts to ensure that the lessons are not lost.
