Not disagreeing with you on the Ukrainian people deciding for themselves. I was focused on the optics which are meaningful, especially when you are dealing on very sensitive grounds.
On Nuland, everyone seems to be conflating "biolabs" with "bioweapons labs" to score points. I wrote biolabs or biological laboratories, as did the NY Times. She said, "she is concerned that Russian troops will get their hands on the research materials." That means test tubes filled with nasty things we don't want released.
I am not so much focused on why there were there. There seem to be legitimate reasons to be via previous treaties. My concern is why were the contents and research moved or destroyed prior to the invasion? There should have been strict protocols in place to do so given the situation before the invasion.
It's just another think to put on the post war pile of "what have we learned from this" and who is to blame.
