You are obviously aware that “we” do it all the time as well - but no sane intelligence agency will go out shouting in press “WE DID STEAL CHINESE OFFICIALS’ EMAIL FOLKS, OUR AGENTS ARE TOP CYBERCOMMANDOS AMD LAST WEEK WE TOOK OVER A COMPUTER IN IRAN AND RECORDED THEIR MINISTER’S SECRET MEETING” Though actually Americans did go out shouting once recently, calling out Russia before they invaded Ukraine and making sure everyone gets the message “we know what russia is up to and we’re ready”. It was considered an extraordinary strategy when the sitting US president effectively broadcasted military intel.
