If you don't mind, I would say Adolf Hitler or Usama Bin Laden. Of course, their inspiration is little off the road/airway but still they did what they supposed to do for THEIR Countries.
Gandhi is pretty inspiring if I talk about my patriotism.
Just so you know, there was a book published last month which had most 100 inspiring people in the world. UBL's name was on that list but Bush was no where to be found.
