@NJ5. Nuclear weapons aren't secure/not secure. If Highway's conjecture is correct they will merely be going from very secure to even more very secure.
Edit: And I severely severely doubt that any money will be spent on getting new weapons. Both Russia and the USA are actually pretty desperate to reduce their stocks from Cold War level, they just don't want to do it before each other. That's why there is guaranteed to be another treaty on nuclear weapons reduction within a couple of years.
