An excellent analysis of our military, penned by Dimitri Orlov, is a good read, something along the lines of what BRT has written about regarding fubars like the F 35 and digital weapon systems that go rogue at the most inappropriate times. Asymetrical warfare kind of says it all here.
In general, if the objective is unrealistic, it doesn't matter how much money is wasted in trying to achieve it. More specifically, it's a lot cheaper to break something than to make something work, and the US military, no matter how much money is spent on it, remains quite cheap to neutralize. For instance, a Nimitz-class aircraft carrier costs somewhere around $5 billion, while a Russian Kaliber missile that can be launched from a fishing boat from 1200 km away and destroy it is competitively priced at $1.2 million apiece. To put these numbers in perspective, Russia can wipe out the entire US aircraft carrier fleet without exceeding its military training budget for the year.
Read the entire piece, you will be stunned at just how stupid the US can be regarding weapons procurement. IMHO, this fits right in with "W's illegal Iraq war and Hillary's excellent adventures in Syria and Libya if you know what I mean.
