he saw it with his own eyes. >> stahl: he saw this. >> spielman: he saw this. >> stahl: that's a bitstretch-- archeologists tell us that no one has found any evidence that abraham was ever here. it's controversial that the city of david uses discoveries to try to confirm what's in the bible, particularly from the time of david, the king who made jerusalem his capital. >> spielman: people believe that when king david captured the city, he snuck underground through this tunnel, which led him underneath the city wall up into the city. >> stahl: half a million tourists visit the site every year with guides who try to bring king david to life. there's an implicit message that, because david conquered the city for the jews back then, jerusalem belongs to the jews today. today, i've seen scores and scores of soldiers coming through. >> spielman: it's part of their cultural day to try to learn about what they're fighting for. and when we bring them here, they understand that they're not just fighting for today; they actually represent the return of the jewish people to israel after thousands

lesley stahl read this on her vacation and wrote me a nice letter. she said she found it engrossing, creative, and funny. i said, "i'll take all three." ( laughing ) >> hinojosa: but you're all about grassroots and every citizen can change, and... >> yeah. >> hinojosa: so isn't this kind of saying, "wait a second. so we can't depend on the grassroots. now we have to depend on these ultra, ultra, ultra rich who may have their own baggage," but they're the ones who are going to actually make our country better, or our world better? >> yeah, i selected them because they're enlightened, in advanced stage, had a different perspective on life, and had a lot... were willing to put billions of dollars into mobilizing the grassroots. so it's the top down, bottom up. justice requires money. it requires money for lawyers, for organizers in the communities. it requires money for transportation. it requires money to constantly reach people directly. and people don't understand. the abolition of slavery movement? a lot of it was funded by proper bostonians in the

. >> and this is my last bill gates question, i'm not going to leslie stahl my way. but you guys have your question cards so please feel free to write questions and we're going to gather some later but actually i thought the most interesting passage when you wrote about bill gates in the book when you wrote i left microsoft a quarter century before bill did and we both had our signal triumphs but in certain respects neither of us has been quite as good alone as we were together. so i'm reading this and i'm thinking, wait up is he trying to say what would have happened if you would have stayed at microsoft? what would have happened, you know, in the past 10 years that's been going on that microsoft has fallen by the wayside, not the wayside but clearly is facebook and twitter or google, do you ever think what would have happened if you would have stayed? >> you know, i've i thought about it. in technology, we just accomplished some amazing things. and bill was an amazingly -- to use microsoft language hardcore business person and the company did super well certainly i
