==Financing militaries== Military budgets often reflect how strongly a country perceives the likelihood of threats against it, or the amount of aggression it wishes to conjure. It also gives an idea of how much financing should be provided for the upcoming fiscal year. The size of a budget also reflects the country's ability to fund military activities.<ref>[http://www.statista.com/statistics/203090/defense-expenditures-of-the-us-per-capita/ Statistics on Defense Expenditures in the U.S. per Capita, 1990-2011], NATO, April 2012.</ref> Factors include the size of that country's economy, other financial demands on that entity, and the willingness of that entity's government or people to fund such military activity.
