Your profile says your a supporter of the troops and I have no reason to doubt you there. So I will just go against your warning and try to tell you that the space industry, like nuclear energy industry, is dual use. As such, the research and products that come from it, whether you are aware or not, contribute greatly to our national defense. NASA funding provides a huge chunk of this.
You might want to focus your spending complaints on the more obvious waste of welfare and wealth redistribution.
Never really looked at it that way. I never put the space program in the same pocket with supporting the troops. There may be some military people involved with the space program. Your right the welfare and wealth redistribution is worse waste of funds than the space program.
