"[M]oral leadership is more powerful than any weapon... That is why I am speaking to you in the center of a Europe that is peaceful, united and free — because ordinary people believed that divisions could be bridged; that walls could come down; and that peace could prevail." (Obama Prague, Sunday)

"Human destiny will be what we make of it" (Obama, Prague, Sunday)

"Moving the ship of state is a slow process... States are like big tankers. They’re not like speedboats." (Obama, Istanbul, Monday)
