I’d like to recommend the Strategic Security blog of the Federation of American Scientists (FAS) to you as a resource for keeping up with national security issues, particularly arms control of proliferation issues. The successful signing of the missile defense deal with Poland this week means that this issue has now returned to the forefront of the international agenda and it's important that Americans understand this issue. Here is how FAS describe themselves from their About page:
The Federation of American Scientists (FAS) was founded in 1945 by scientists who had worked on the Manhattan Project to develop the first atomic bombs. These scientists recognized that science had become central to many key public policy questions. They believed that scientists had a unique responsibility to both warn the public and policy leaders of potential dangers from scientific and technical advances and to show how good policy could increase the benefits of new scientific knowledge.
I like this blog because it offers more technical information than the standard mainstream news media reports, it's written by scientists and allows you to appreciate some of the complex issues that get forgotten in the popular debate over these issues. If we are headed toward a new Cold War, we will need to be educated all over again about nuclear weapons, warheads, ICBMs, MIRVs, and all the other terms that have faded from our national consciousness over the last few decades and this is a great place to start.
