Err...ok? "Aggression" is awfully ill-defined. Would Bill Clinton's intervention in Haiti then be equivalent to Russia's conquest of the Crimea?
The standard in practice is established in the Nuremberg and Tokyo trials. Rescuing citizens from apparent danger (Grenada, Panama), supporting one faction against another (the USSR in Afghanistan) is not so clear. In Haiti, the American intent was to restore a lawfully-elected government.
Chavez was and Madura is dreadful. Political leaders have been convicted of ravaging their own economies, but those who do so often are convicted of more murderous crimes than extortion and embezzlement. It's even more blatantly plunder when a foreign power transfers private or public property to the foreign power or to privileged institutions within the foreign power.
Human rights are getting much shakier in America than they have been at any other time in American history. President Trump has constituencies that would support the stifling of dissent or postponing an election. His trivialization of violent, fascistic cliques is without precedent. Ask how things are three years from now -- or three-and-a-half years from now should he be re-elected.
