Com o teste nuclear da Coréia do Norte, talvez valha a pena reler este artigo:

100 years ago Einstein discovered $E=mc^2$, the secret energy stored in ordinary mass. $\Delta H = D(H-H)$ is the chemical energy released in chemical bond formation between two H atoms. The failure to recognize the enormously different energy scales in those two equations reflected in current events may start a chain reaction this very year, on the one-hundredths anniversary of Einstein's discovery, that leads to the end of civilization. Due to the confluence of a particular set of circumstances, this particular moment is more dangerous than any other in the history of nuclear weapons. Physicists have a special responsibility to do their utmost to prevent this from happening. This paper is a call to arms. A principle to underpin nuclear non-proliferation and enhance stability is advocated.
