There are literally thousands of options. DPW creates wholly US-owned subsidiary - or one with controlling interest if not wholly US-owned. Individual operation could be sold off to business consortiums already in the business. Neighbors at various ports may have an interest, etc.
Whatever form the "new deal" takes need not resemble the proposed P&O -> DPW transfer.
Thus making an already convoluted business arrangement even more convoluted. Well I guess that's the best that be done on it. It would have been nice if these "gentlemen" and I use the term loosely had thought of this two weeks ago.
