Big difference to have the earthquake or its aftermath killing you vs. the US military killing you.
This is not analogous to airdrops(?) in WWII. At best, the helos arriving can sling load supplies, that would keep the casualties down. But they are a way out yet. This is part of the tragedy, the Haitian gov’t is such a POS that they have to wait for aid.
At this point, time is a killer, in the most literal of senses.
