If you have to ask.....
It's quite simple, we are a tool, use us to fix something and the thing works, then great. Use us and we break something we shouldn't then we are a damn sorry tool.
More pointless hyperbole to cover up the fact that you can't answer the question.
It is clear to me that you are just a detractor. You claim to be in the service but I don't believe you. If, on the off chance that I am wrong, and you are actually in the service, please resign your commission. I don't want someone like you defending our nation with words rather than might. If you think your (dim)wit is so powerful use it somewhere else. It won't save the future of America and it won't stop bullets.
