To put it simply, they're not allowed to have nukes, period. All because they started WW2 and we don't want it to happen again. Meh, less nukes in the world is better anyway...
I think you'll find that has nothing to do with it. They don't have nukes because they signed the NPT and stick to it. They do have a functioning nuclear industry though and could quickly assemble nukes if they had too.

Germany - While Germany is a signatory of the NPT, it has the means to easily equip itself rapidly with nuclear weapons. It has an advanced nuclear industry capable of manufacturing reactors, enriching uranium, fuel fabrication, and fuel reprocessing and it operates 19 power reactors producing one third of its total electrical needs. On the other hand, Germany has since 1945 made no serious attempts of acquiring or developing its own strategic delivery systems. Considerable numbers of nuclear weapons have been stationed both in East and West Germany during the Cold War, starting as early as 1955. Under the nuclear sharing scheme, West German soldiers would in theory have been authorized to use nuclear weapons provided by the US in event of a massive Warsaw Pact attack. Several dozen such weapons reputedly remain on bases in western Germany. Since 1998, Germany has adopted a policy of eliminating nuclear power, although slow progress had been made.[36] On January 26, 2006, the former defence minister, Rupert Scholz, said that Germany may need to build its own nuclear weapons to counter terrorist threats.[37]
