as the argentine head of state my proposal is to build a gigantic fleet of submarines both big and small, to better enforce our antarctic claim, and as training we will hunt down all the chinese fishing ships (even the ones outside our waters, they cant complain because theyre illegal anyway)
and then as the 2nd leg of this proposal, we will create the nuclear bomb, which we've already possesed the know-how, resources, and facilities for since the 80s, with all the nuclear plants and uranium deposits (and we even have a heavy water and also nuclear enrichment plant in bariloche which exports to other countries including brazil)
to top it off, we will combine the sub fleet idea with the nuke idea, and send huge secret cargo submarines to north korea, iran, russia, china, etc. to acquire ICBMs and ICBM parts from ANYONE who will sell it to us, and thusly we will have 1st strike capabilities so the USA wont invade us
and then after a decade or two we will be able to have nuclear subs too for the 2nd strike capabilities
