We may split on what Obama should say or do, fearing the effects for the protesters or our nation, but that should not stop Americans from demonstrating solidarity. Last month I attended a candlelight vigil to honor those who died fighting for freedom. The gathering was somber yet hopeful, but it was still too narrowly Iranian. We need more Americans — African Americans, Asian Americans, conservative Americans, liberal Americans, red-state Americans, blue-state Americans. If there is one issue that politically polarized America ought to be able to rally around, it is the gallant struggle of Iranians.
