I do not think the Federation needs to be
destroyed, but I think some internal political turmoil--some serious self-examination--is in order to flush out the immense amount of political detritus (bad precedents, bad politicians, possible unconstitutional decisions and legal code). Some unrest may be very beneficial.
Actually, I think the best thing that could happen to them would be a
credible rival. Not another "we want to conquer the galaxy" type rival, but a political and trading adversary that offers a different but
legitimate point of view. Something that has to be given serious thought and cannot just be dismissed out of hand.
