Actually I think I would agree that LANL deserves the adjectives. It has an annual budget of about $2G, and its primary job is the maintenance of the US nuclear arsenal. CERN and the LHC is pretty impressive, but the sad reality is that military and black projects are often an order of magnitude bigger than even the most advanced civilian entities. With the completion of the LHC CERN's annual budget will be about 250M Euros for LHC related work and an additional 60M for the rest. About 450M USD. So less than one quarter that of LANL. Since about 75% of LANL's budget is for the arsenal, we reach the conclusion that LANL's "other activities" budget is much the same as CERN's entire budget.
As to sensitivity, on a world scale it is hard to imagine a place more filled with information that could cause catastrophic issues on a world scale. When it comes to building weapons of mass destruction these guys wrote the book. Sadly the current changing on the world political scale seem to point in a direction where these capabilities might regain some of the importance they once held. (It has been observed that a big problem at LANL has been a perception that they were becoming irrelevant, a world stage in which the arsenal they maintain was becoming unimportant.)
