Is it possible (even remotely) to achieve peace using social media and modern communications?

I saw this on ted.com and was moved and inspired. Ronny Edry, a graphic designer, shared a poster on Facebook of himself and his daughter with the message: “Iranians…we [<3] (heart) you.” By initiating communication where it was once forbidden, letting the people of “enemy” nations know that they are loved by the ones who are supposedly their enemy, a chain reaction of love was started, showing the world that the peoples’ opinion is not always the same as that of their governments. The reaction came not only from Iranians, not only from other Israelis, but also from residents of the US, Australia, from Palestinians, Europeans of every sort, and soon the message became viral.

Could this be the tip of the iceberg of a new “pacifist” movement?
