The removed setence "Between 2001 and 2007 just R$11.1 billion, roughly US$6.1 billion, were invested in the military." has source. 

The source is "O dia" http://odia.terra.com.br/brasil/htm/pais_gigante_defesa_pobre_133990.asp offers IMO a unique perspective on the ammount that has been invested over the recent years.

Could I add that sentence back?
