Come on get with the times pal, they aren't busy bankrupting themselves, they already did that in 2001 when the economy crashed. The Peso went from 1:1 with the Dollar to about 4:1 where its currently sitting steady. At the time many places wouldn't accept Peso's but would accept any other stable currency, especially US Dollars and GB Sterling Pounds.
Also at the same time kidnappings became the in thing for a country that has no Job Seekers Allowance, and no National Health Service. If you had money you were at risk of being kidnapped, or your kids being kidnapped. At the Airports they would search people not for guns or drugs, but for money to stop them trying to take it out of the country. My wife was stopped and searched 5 times going through the main airport. (She flew out to Argentina the day after 9/11 and came back a few days before Xmas.)
Its much more stable now. The economy has mostly recovered although the exchange rate is still low, but its much better than it was.
And no they aren't liable to start a war. That was the Military Junta that was loosing their Dictatorship grip on the country and did a Bush/Wag the Dog and started a war to try and stir up popularity. Yes someone people still grumble about the Falklands/Malvinas but they are more interested in getting the former Junta members who made thousands disappear during their dictatorship.
