I think you are confusing your reluctance to sell, with their reluctance to buy. I would only offer to sell T45 if this assisted a sale of other ships, I think they have a wow factor which would impress anyone who went aboard. However if they were not interested I would have no desire to sell.Brazil wants a carrier-building capacity for the same reasons as India, France, China, Russia, the USA or us - to build its own carriers, free of any interference from anyone else - and also to show that they can. Brazilian shipbuilders want to build carriers because they want the work. Their workers will vote for congressmen who'll vote for indigenous building. POLITICS.
The trouble with your approach is that you're picking fights you can't win. Remember what happened to Napoleon in the end.
You've acknowledged that trying to sell what you have, rather than what the customer wants, is doomed, but you still insist that we should do it. Brazil has a long-term naval development plan which specifies commonality, local building, value for money & 'good enough'. T45 doesn't fit into that. To succeed, we need to offer what they want - and it ain't CVF, T45, or Astute!
You talk as though Brazil has a massive military agenda and budget, yes there is a desire to locally build but she brought Foch recently and if the money is right then a deal can always be had. The money will be right because as we know (you might not be able to accept yet) a CVF will be sold. I agree this is painful to accept but we have to move on. The focus now should be to ensure that we get one carrier in service ideally before 2020. Unfortunately you are so accepting of anything the MOD/RN says you accept this as fact. Believe me this is not the case.
Ask yourself this simple question, had it been possible to cancel both carriers at less cost than completing them would the Government have cancelled them or not??
Secondly will the RAF be supportive, indifferent or hostile to the commissioning of a CVF with F35 onboard?
In the light of the answers to the above the RN must be much more flexible in its approach to procurement of new kit, and supporting of its industrial base. Quite frankly eveything should be up for sale at a reasonable price (building replacements later is not a big issue and will help maintain production/employment). You many be right on the T45, but a CVF is a real possibility matching timings/cost. It does look like the French are in on the SSN but it there is a chance of an Astute we should go for it.
When you recount the shopping list of the Brazilian Navy they will be flexibile to cost saving opportunities even if they are not all locally built.
