Keep in mind, friends, an arms race or a "building up of our (already giant) defense system" has more to do with making money for a small few (again) at the expense of the masses (again).
It creates what is called an Iron triangle: Money Goes from the government (budget) to research and developement of new weapons, which goes into the pockets of private entities who are the ones who do the research and developement. Then these entities take some of their wealth an allocate back into the pockets of politicians (campaign finance, PAC, lobbiests, etc., etc.) which in turn pressures these politicians to keep our defense budget high, and to keep dumping money into research and developement.
Government >> Companies >> Politicians
That is the triangle.
What people don't like to think about is where the money is coming from? It comes from our tax dollars, of course. So instead of keeping health care costs down or nationalizing some sort of plan, instead of making sure our troops are equipted with what they need (including equipted with high enough salaries to take care of their families back home), instead of making sure schools have what they need, etc., etc., and ridiculesly etc., this is one of those things that millions of our dollars gets to be spent on instead.
Now, I know what some Yay-hoo is going to say next. "But we need to keep researching and developing new weapons so we can make sure we can defend ourselves." Well, this is wrong.
All countries need (I hate to use the word "need" here) to keep things neutral in terms of nuclear war is what is called "mutually ensured destruction." Mutually ensured destruction is where both you and I have enough nukes to mutually destroy ourselves. If anyone launches Nukes on the U.S., we have enough nukes to tag them and hard before we are hit. And since we are talking about the U.S. here, we have enough nukes to tag EVERYONE about 10 times over before we are hit.
So, countries who care about their own well being will NEVER hit us with a Nuke, because we can mutually ensure their destruction. And that's all there is, folks. No hypathetical missle shield system will change the fact that we have enough to mutually ensure destruction not only on the entire world, but certianly on any country who wants to try us.
So, there is no need to spend money on research for cooler nukes; we can allocate the money to actually support our troops who are fighting, then reduce the rest of the budget. Yea, thats right...reduce.
However, there are some "loopholes" that people will try to use to justify not reducing our military budget, and not reducing the amount that we spend on reseach and developement.
#1. Now, there is the trump card of groups who don't care about their well being at all, ie. terrorists. Our resources need to be focused on making sure groups like that aren't going to get their hands on something that could really hurt us, instead of focusing our resources on research for cool new weapons that we won't be able to use for another 15 years, or on taking over countries for oil.
#2. Because of groups like in #1, political figures use this to justify for developing anti-nuke programs such as "star wars programs." The problem with these programs is that if they ever work, they violate other countries abilities to mutually ensure destruction of us. So, we can nuke them, and they can't nuke us. This may seem great for us, but it is not. All this does is cause other countries to research and develop their weapons programs to beat our anti-missle programs, thus creating another arms race.
So don't look at countries like Russia all pissed for developing more weapons, when we caused it.
Now, if it was true that these lobbiests and political figures were truly concerned with being nuked and that is why they think we should develop anti-nuke programs, then they wouldn't want to do it through large quantities of our tax dollars. They would go to the U.N. (yes, the evil U.N.), start a collition were many countries with nukes put in money and research anti missle programs, and we all get to share the technology. Then, in 50 or 100 years, if an anti-missle shield were to ever work, we'd all be able to mutually defend ourselves.
It's just an idea, although I don't really think it will prevent an arms race, so the details would have to be worked out. Regardless, the reason why you don't see politicians trying to work ideals like this out is because they care more about making money for a small few off the project rather then really protecting our country.
So, yes, once again, it's all about the money.
