There are dead, dying, sick, hurt, homeless, and starving people. Men, women, children. It is a medical and humanitarian crisis of stunning and unprecedented proportions, exacerbated by an inept, incompetent, and corrupt government.
I think that what needs to be done should be done. Screw visas -- people, a lot of people, need help.
I suspect that China, India, Thailand or even the US Marines could insure aid was available to those needing it.
