It is up to Gaddafi to decide enough is enough:
NATO's most senior military official said on Tuesday that it was up to Muammar Gaddafi to decide ``enough is enough'' and the alliance would continue its air strikes until the Libyan leader respects the United Nations resolution.
The Libyan people are clearly sending as strong a message as they are capable of doing that it is time for (Moammar) Gadhafi to go.
