So, let's reach a conclusion. This image is the "real" nuclear suitcase. Why ' because it has a spherical tokamak. So you to understand...and why, some intel media, always putted the question about Lebed claims...its because the traditional nuclear bomb, is a fission bomb, meaning chocking particles, their biggest problem ever, was stabilizing the weapon, and the first invention was van graaf device! however, carrying a nuclear "fission" device is close to impossible, because of stability; therefore, the nuclear suitcase is a "fusion" nuclear bomb; "fusion" is separation of particles (the opposite of fission) that natural occurs on nature, and so it doens't poses the stability problem; Then, this sphere is a hallow steel sphere, called a mini fusion reactor. Conclusion, 1970th nuclear suitcases are actually a myth; only in 1995 they start having some workable one's. Anyway, the true smuggling of this, is to be done, by lunching small undetect missiles, close to the ground , and deliver the suitcase inside of the cap.
