Folks, this may be a spoiler.  However, I think that this is the way V  will go.   The vistors have  a single program, that of getting the resources that they need for their homeworld to survive.  In order to achieve their goal they must cure all human diseases (through a universal health care program-single giver) and eliminate world hunger and gain the trust of everybody.  Their goal is to serve mankind.  Eventually, we will discover the details, probably slowly at first and discover that the goal is to truely serve mankind-a cookbook probably in a .pdf file. After all no decent alien reptile would even think of eating diseased food, but that is after getting the food to mine the natural resources also needed.  Jan
