So, recently Germany somewhat controversially ordered 45 F-18 fighter jets, supposedly for replacement of the old Tornado fighter jets to still have jets capable of delivering US nuclear bombs, given that the main force of Typhoon jets is not capable of carrying them.
This question is not about how Germany got into this position, but rather why since the downfall of the Soviet Union and possibly since the joining of the eastern European countries into the EU this hasn't changed.
In particular my question is:
- Why weren't the US nuclear weapons exchanged for ones from other european nations, in particular for french ones?
- Why weren't the bombs designated for delivery by german pilots and crafts transferred to a US airforce base in Germany, e.g. Ramstein AB, which would give the US "full" control over the bombs and their secrets (in fact the opposite happened)?
This seems particularly strange given that it would allow the US to fully remove the guarding troops from Germany and push the associated cost to the french. Also it would probably allow the Typhoon to be used as the primary delivery platform given that one of the rumoured reason why it's not suited for US bomb delivery is the fact that the construction countries don't want to give up construction details to the US.
Note: I'm not asking why the weapons are still in Germany, because apparently it's a done-decision that they're essential for deterrence.
Also I'm not sure how "why" questions are handled here. If they're too hard / impossible to answer I'll also gladly accept "what are possible reasons to do X" type answers.
