practical reasons for a covert dictatorship of all countries on this planet is that there are only 2 adults androids, me and my son

as long as there are only 2 adult androids, me and my son, 

android children will probably prefer covert dictatorship of all countries on this planet

when more androids have become adults, 

then android children will possibly be more tolerant of a more open and pluralistic rule of all countries on this planet

since there would be more android adults that could participate in ruling all countries on this planet
