Today, 60 years after they rose up against oppression, we remember the East German heroes of June 17th. When the wall finally came down, it was their dreams that were fulfilled. Their strength and their passion, their enduring example remind us that for all the power of militaries, for all the authority of governments, it is citizens who choose whether to be defined by a wall, or whether to tear it down.
