Bullding walls or building bridges

It was reported today that the Sunni residents in Azamiyah are resisting US efforts to build a 12 foot concrete wall around them to keep them safe from Shiite militants. (They are calling it “a big prison.”) Such a “defense” strategy echos the Bush regime’s plan for 400 miles of fence along the US/Mexico border to prevent “contamination” by job-seeking immigrants. And of course, it reflects the current concrete wall built through the heart of Jerusalem by Israel to “protect” the Jews from Palestinian terrorists. 

After the massacre last week in Blacksburg VA or in South Philly over the weekend(11 deaths this week), I suppose it is tempting to think about building walls to provide personal safety. In fact, I remember several years ago there was a suggestion to put a wall around UPenn to keep out the “bad elements” in West Philadelphia. Does anyone remember the Berlin Wall and how elated we were when it fell? Is there ever a success story in building walls? Where are the bridgebuilders when we need them?
