a government official, elected or otherwise, will most likely side with the isolationist rhetoric, if only for votes next election.
The new questionably-elected president keep the appearance of defending a brave isolation that only he is capable of (Even though the coup in brazil was caused exactly because the previous government, corrupt or otherwise, was denying american companies access to new oil reserves already), when in reality he is eating in trump's hand. He just appointed his son, who until before the election was working as a fast food chef in florida, as the brazil ambassador in the usa.
So, yes, a country should be independent and look out for the people. But in this case it is only propaganda/fake news/disinformation. whatever political campaigns are called today.
