If this attack results in actual loss of life, I firmly believe the US should ensure that there are real-world physical consequences for these criminals. They cannot be described as anything less than the worst humanity has to offer. A failure to respond with meaningful and severe consequences for those responsible (assuming this is attack can be confidently attributed to a particular threat actor) opens the floodgates. Time to find out how seriously the US takes its own cyber doctrine.
