Can anyone name 3 Reasons why Rudy Giuliani is a good leader?

I could`nt have imagined any other person as Mayor during 9-11 he made America proud again aswell as making sure the fallen were not forgottenandsurvivors taken care of not to mention pouring millions of his own dollars into charities thus pushing his rich friends to do the same, Last I heard Rudy was responsible for close to a Billion dollars of generated funds given to help the people affected by 9-11.
