In Iraq its not as much a refusal to buy Iraqi goods as it is a blockage of Iraqis buying goods from outside and restrictions on what goes into the country. Sanctions only harm the common people while the rich of the country like Saddam and his followers live like Kings because they already have large fortunes and because of their power they can force people to do anything for them or they can take what they like. UN/U$ sanctions on Iraq only affect the poor as Saddam refuses to spend any of his own fortune on the people of Iraq.
There were two “Reigns of Terror,” if we would but remember it and consider it; the one wrought murder in hot passion, the other in heartless cold blood; the one lasted mere months, the other had lasted a thousand years; the one inflicted death upon ten thousand persons, the other upon a hundred millions; but our shudders are all for the “horrors” of the minor Terror, the momentary Terror, so to speak; whereas, what is the horror of swift death by the axe, compared with lifelong death from hunger, cold, insult, cruelty, and heart-break? What is swift death by lightning compared with death by slow fire at the stake? A city cemetery could contain the coffins filled by that brief Terror which we have all been so diligently taught to shiver at and mourn over; but all France could hardly contain the coffins filled by that older and real Terror... --- Mark Twain
