This is a TERRIBLE article. It reads like neo-con propoganda screed - not a encyclopedia article. While I do not have the expertise to fix even the obvious mistakes this artcle needs a huge rewrite to remove factual errors, unsupported statements, obvious bias, and other errors.
See http://www.reference.com/browse/wiki/Sandinista_National_Liberation_Front for an example of what an article should look like.
