Brazil & Argentinian cooperating on becoming a regional power tandem.

With all the sabre rattling wrt the Falklands, and the aspiration of Brazil to become a regional power, how likely would it be that both countries cooperate to become the real power in South America to replace the USA?

Brazil is working on a few platforms that would completely twist the balance between Argentina and the UK in the Falklands affair:

KC390 transport that could be converted in air tanker to ease air operations and to make an air bridge.
R/P99 AEW, singint and maritime surveillance aircrafts that would be paramount to the decision makers.
And most importantly the development by Brazil to build it’s own nuclear submarine.

Both navies have an aircraft carrier which enables them to keep currency in carrier ops (a thing that the UK doesn’t have for instance). With India launching their own carrier program. Why wouldn’t Brazil and Argentina as a junior partner to join with India on the programme. If you add 3-4 ships to the Indian program, it could become pretty affordable in the long run, and they could even manage to export a few of them to other countries like Singapore, Malaysia… on the cheap.

The same could be said of the nuclear subs. If Argentina was able to add, say 3 brazilian built nuclear subs, it would mean that the UK would have to multiply its investment to keep the falklands severalfold, which could become just too expensive for them in the short to medium term.

But now we come to the part that interest us: fighter aircrafts. I say both countries should make the bid to buy the EAU+Qatari Mirage 2000s, along with full ToT from Dassault. You could deliver about 24 to Argentina and 48 to Brazil. Embraer should be given the right to build spare parts, and the source codes to integrate weapons of several origins (russian, south african, israeli, and of course brazilian & argentinian).

Argentina: 24 Mirage 2000-5/9 + 12 Mirage F1M (upgraded to ASTRAC standard if possible).
Brazil: 48 Mirage 2000/9 + 12 Mirage 2000 B/C (why not upgrade them to the 9 standard).

Training for Mirage 2000 & P/R 99 could be pooled, and carrier force and submarine force training could be pooled too which would lower the costs drastically.
