And regarding the hostility issue, I can tell you that people have negative feeling towards the US government ( not the people though ) but basically because of supporting the british during the Falklands War, for requiring a visa to enter the US after years of being into the visa waiver program, etc. A lot of people dislike Chavez and the love the current government professes for him, so I don´t think it will affect americans living here at all. Despite the valijas incident, this government ( both Cristina Fernandez and Nestor Kirchner are ex montoneros, left wing, pro communists, anti imperialists ) so if you haven´t percieved any hostility until now, I don´t think this incident would worsen things, I don´t think the argentine people have any type of particular sympathy for Chavez or Fidel whatsoever.
