While TrumpUSA is proving to be empty... on a short lease for obvious reasons.... he does illustrate a few things.  The system that produced the TrumpUSA phenomenon can no longer "lead".  It is doubtful that this situation would have emerged without the ill-considered but necessary intervention of Bernie, without the unbelievable corruption of the Clintons... But it did happen and now the USA has to focus its strength on wriggling out from the mess they have self-inflicted.  They cannot even lead themselves politically and no other country is lining up for anything from the USA except money.  They cannot afford nor profit from their situation and have been wandering around in a void for decades.  Leadership exists when people want or need it.  It cannot be forced on anyone.  The Chinese offer it.  TrumpUSA (so far) are trying to grab it.
