What exactly could we do about it if there was evidence?
A reasonable consequence of such a thing would be an act of war to destroy the facility and the Government that did such an incompetent job of operating such a dangerous program.
We are, of course, completely unable to perform such actions with any prospects of success. Moreover a number of our key political authorities have obviously been bought (or at least rented) by the Chinese. So, our guys go along with the Chinese story that "there is no evidence".
It is too unsettling to admit anything else.
“We are, of course, completely unable to perform such actions with any prospects of success.”
Ignorance.
That is why I did not include any particular party that was doing the admitting.
