Rescue Efforts don't Come with the Directive: 'Rescue Yourself'

  I consider on the suggestion that rather than allowing the migrants into the U.S., we should teach them to fight for the betterment of their own countries. Am I fair to make this comparison: Suppose someone was attacked in an alley, and the cops came along just then, and -- seeing the person was in danger -- tossed them a knife, saying, "You need to learn to fend for yourself."
  It is said, "Never take a knife to a gun fight," and I'm not so sure but what asking them to stand up and fight the gangs and governments comes with the same level of expectation.
   Rescue efforts don't usually come with the directive, "Rescue yourself," but that's what we're asking them to do.
