A diagram of a weapon with a 50KT yield is just another card in the deck of destruction. This would be a weapon with triple the yield of the bomb that destroyed Hiroshima in 1945. There is no way that the world can allow Iran to acquire nuclear weapons. There is no legitimate need for Iran sitting on an ocean of oil to have a nuclear reactor. Personally I am rooting for Israel to settle things by destroying Iran's reactor and taking out key individuals in their WMD program. Kill this threat!
