From whence? and where? and who?

From where do the weapons come--the ones which kill all the people who die due to the use of weapons?

How many people, among the ~180,000 who die each day, are killed by weapons of warfare?

Who gets the money spent on these weapons? And who spends it?

Who builds the weapons? And where are they built? And how much does the building of them prop up or contribute to the local economy, in those places? And do they/we realize this, or have answers to any of these questions?
