Who killed the Monks?

Burma has fired on the protestors of Burma, killing monks amongst other people While it is the soldiers who have done this, the junta leaders are behind every trigger that is squeezed. But who else is helping put those shattering bullets into the bodies of civilians? Whoever sold the weapons that are being unholstered by the army. These sellers whether they are Russian, American, French or Japanese have the blood of Buddhist monks on their hands.
In the weapon selling business, the manufacturers can talk about targeted, efficient, strikes etc but at the end of the day who usually gets killed by these guns etc? It is the children, the monks and the protestors. Whether they are in Burma, Africa or Iraq.
In a 21st Century world, it is time to wipe out the manufacture, sale and use of weapons. We surely must have learnt other means of diplomacy by now?
