What is the best role for citizen voices in foreign policy?

A View From The Cave will be co-hosting today’s question so feel free to check out the discussion over there as well. Here goes:

There are views along a spectrum about the appropriate role for citizens in the foreign policy process. On one view, citizens should focus solely on “noise-making”  – akin to the ‘bumper-sticker’ model the Save Darfur movement was pursuing until 2006. Under another view, citizens should be pushing for specific policies generated by advocacy leaders – akin to the model the Enough Project follows. What are the risks at either end of the spectrum? What would be the challenges in pursuing a middle-ground?
