CoD 7 probably isn't just Vietnam based, it'll probably start in the 60's and climb up during the cold war. We can expect a nuclear warhead appearing in the game because during the teaser trailer, the element, U-235 was shown. U-235 is a fissile isotope that is generally unstable. It can be used in nuclear warheads. Also, U-238 is Uranium 238 which has a half-life of 4 and a half BILLION years. In the trailer, it showed the nucleus being cut in half. When U-238 is cut in half, it can be used as nuclear fuel and will eventually result in a nuclear warhead. It will have something to do with a nuclear warhead. There's probably gonna be a back-story in corrolation with history that involves spying and recon missions.
