I know. I understand the induction. I still don't understand what the statement that at least one of them has green eyes changes.
They all know this and they all know that all the others know this as well.
To be successful, the process requires all dragons to be absolutely certain that all other dragons are simultaneously following the same process. The statement doesn't really provide new factual information, but it provides that kickstart that ensures all dragons know that all other dragons have simultaneously started the inductive process. It synchronises them, so to speak.
Without the statement, or if just one dragon was not present at the time of the statement, the dragons can not be certain that all other dragons have started the process, so they can never conclude anything with certainty.
