With the defeat of the Brits at Malvinas, the Junta regain the popular support they had been losing with their undemocratic efforts. Still, fearing for the worst, they establish a fake democracy, where all parties are approved by a larger organization that controls the political narrative. They have spies hunt down and kill montoneros and exiles in neighboring countries.

On the economic end, winning the war would probably end up in a bunch of sanctions being placed on the government from other forces, so they use any finances they have left to bolster the industrial sector and expand manufacturing capabilities to the inner provinces so as to keep production afloat. They also use the new fangled machining shops to increase home-grown military equipment production and quality so as to strengthen their ability to hold against any retaliation. They establish a secondary port city in Malvinas that acts as a stop-gap for seafaring companies to trade in, as well as a military base for the navy to hold their ships in.

As the heat starts dying down, they re-open talks with neighboring countries for a trade agreement, similar to the currently operating Mercosur. This allows them to start exposing the new manufacturing and product quality to external forces so as to incentivize the return of old companies the government had ties with, as well as increasing the wealth of the country in the process. The crackdown on unions and workers' rights associations ensures that all the work is done at the most efficient, cost-effective yet inhumane factories of the west. Still, this means that the value of the peso itself keeps rising, remaining comparable to the US dollar and English Dollar Sterling even into the late 2010s.
