Military spending took a huge leap post-9/11. This leap in spending would have happened with any administration, liberal or conservative, and it's completely acceptable because the attack made on our country that day killed 2,977 American civilians. I believe that Bush did a great job running our country under the circumstances, but military cuts, as you can see from the graphic, are being made. The Pentagon doesn't even need all the money congress is sending them. Have a look at this article:
http://www.military.com/daily-news/2013/04/30/army-says-no-to-more-tanks-but-congress-insists.htmlThe reason some congressmen are fighting this battle with the Pentagon is because their districts
rely on the military industry.
Either way, the military cuts that are underway are reasonable. If you want more money to be funded into our space program, you have to take leadership over the next decade or two by participating in rallies, voting for pro-space representatives, and emailing/calling/talking to your current district representative (whether you're of voting age or not) about the future of our space program and its importance to Americans.
Remember, the key to progress is always an enthusiastic and well-informed constituency. Every little thing helps.
