Why is there no truthful info in MSM news that Americans aren't informed about the 46 warships to Costa Rica?

The responses here are clueless, angry and bewildered as to why 46 warships and 7000 troops have been sent to Costa Rica or the "so f'n what" tea party response. Why don't Americans want to know what is happening in their own country? Ignorance couldn't really be that blissful.
