I'm a little worried about this - once the USA gets disposable robot soldiers there's nothing to stop them waging war in all directions simultaneously...
It is not as if there is something magically american about these robots. Other nations can and do build their own military robots. Also, they are not cheap. They, as of now, require personnel to operate. I wouldn't worry about an army of autonomous robot soldiers. Save that for the movies.
Spend $ not American lives - prefect for the MIC.
