If the reliability of all the environmental crap was so good, there would be no need to exempt the US military from having to comply. But, since it would be bad press for the politicians to have to admit that your son died because when his tank went into limp mode due to (a. a failed exhaust injector in the DPF system, b. bad NOX sensor, c. bad calibration of MAF sensor indicated EGR malfunction, etc. -- Take your pick) it made it easy for an enemy insurgent to climb on the vehicle and burn him out with a quart of gasoline. The fact that the same issues cost you your ability to make a living is pooh poohed as a minor inconvenience for the greater good, despite the fact that your taxes aren't reduced as compensation for being a beta tester of their poorly thought out regulations, nor does the government compensate you for the lost time due to parts unavailability and no ability to bypass the the systems -- even in an emergency. Sorry keep your kool-aid. I guess the heat during the jurassic & cretaceous periods were due to excess dinosaur farts that weren't fixed by catalytic converters & exhaust restrictors in their asses. We may or may not be getting global warming. If we are, MAN has nothing to do with it, we are simply returning to a more normal temperature (from a geologic perspective). Say good bye to the Tail end of the ice age and welcome the new era. Alternatively ... if you lean that way, welcome the terraforming event that is being perpetrated on this planet by the aliens in Antarctica (where all the ozone depletion started) & get ready for the herd culling that they are about to start. I have no problem with clean water & clean air, but for the short time that humans have been the dominant species on land, we are still insignificant actors in the grand scheme, and I refuse to buy into the popular propaganda that we alone are responsible & that our actions will somehow stop the inevitable. Neanderthals & Cro-magnons were probably having this same argument when they noticed the temps dropping & winters lasting longer
