Except in a certain side-channel sense -- any government that discovers a successful attack on an encryption algorithm it regularly uses will know that other parties could have discovered the same attack, and will then need to limit its use of the compromised algorithm. That behavior change will be observed by other parties and will prompt suspicion about a possible vulnerability. Unless the party that discovered the vulnerability stepped up use of the compromised algorithm, but only for unimportant data or misinformation... Oh, security headgames.
