There’s a high chance that the election of Milei is a new epoch in global history and will lead to a rise of libertarian parties worldwide just as labor parties did. By all accounts Milei is shrewd and has a good chance to succeed.
Argentina has a very particular situation and Milei policies hasn't been that much different to what right wingers in other country would do in his case.
Tbh, Milei's policies are not really much different from what sane left-wingers would do in Argentina's case, either...
