This article analyses some political and law-making processes developed in Brazil and Chile as part of the domestic arrival and spread of Cold War logics and the display of legal and repressive measures aimed to exclude Communist Party of national politics. In a very short time was approved the "Defense of Democracy Act" in Chile and Brazilian Communist senators and representatives' mandates were suddenly canceled. Far away from getting unanimous support, these measures have raised intense debates between Right-Wing parties. Here are explored some of these discussions about which Anti-communist strategies should be adopted: liberal União Democrática Nacional' and social-christian Chilean Conservative Party leaders have opposed to the enforcement of repressive laws due to that they were considered illegal, totalitarian, useless, counter-producing and unfair decisions. This research is based on parliamentary sources, personal correspondence between political leaders also as Brazilian and Chilean partisan press.
