US coverups in the wake of WWII

While the acts committed by portions of the Japanese government in the name of research leading up to and during the second world war are unquestionably atrocities, considering that they had already been committed and the information gained from them was available in the world, I feel that arguing against using that information for future medical good purely by virtue of its history is somewhat illegitimate. What I do feel is unacceptable in the wake of those medical atrocities is the way the United States withheld those medical findings, apparently in an effort to leapfrog soviet biowar capabilities and technology. The quoted section from the inter-agency task force on page 41 sums the US position well, which is effectively that the value of the data on biowarfare, specifically the value gained by keeping it secret, surpasses that of making the research public to be able to prosecute the doctors for war crimes. I would honestly have issues with that conclusion even if the research was going to be used for advances in medicine rather than biowarfare, but considering that the United States effectively covered up data about an atrocity and research into how to efficiently commit war crimes so that they could learn how to commit those same crimes is absolutely ludicrous, and completely ethically unacceptable.
