and the Germans were very eager to sell to us.
"Were", doesn't mean they still are, since Pakistan and Germany have changed since 2009. Pakistan then was a difficult country to sell arms to and the government quite some time to get all necessary approvals, but it's even more difficult today, with the situation in the country being more unstable.
Also the current German Minister for economic affairs, is pushing a very restrictive arms export policy ,which makes it hard even to sell weapons to countries like Saudi Arabia or Indonesia, which not only have the money, but politically are more regarded than Pakistan.
So if the French back out (and they generally are ready to sell to anybody), it makes it more than difficult for the German government to justify a sale to Pakistan, on political terms in the first place, let alone the financial issues. Also, the last time the French stated ToT related issues for not selling stuff, was influenced by the US government and if that is still the case, that influence is even stronger on the German.
Btw, U214 is not just the export designation, but is the export sub, which by design is based on the older generation of German U209 subs. It shares some techs and systems with the U212, but still has credible differences.
But doesn't it also tell something about PN's confidence in Chinese subs, when they after 6 years still are trying hard to get western subs, against all political and financial odds, when the Chinese subs and loans should be far easier to get?
