Probably every building of any value will need to be razed in the coming days and weeks, after the families have all counted their dead and the work of rebuilding begins.
Scientists say future shocks in the area could be worse than this one. This means taking Haiti's building codes from the bronze age into the 21st century.
Doing this will employ countless people, and the rigors of the math required to build quake-resistant buildings (for schools and other public buildings at the very least) will force the nation to invest in the education of their youth. What other future can a country shaken to its core look forward to if not a brighter one?
This is an opportunity for Haiti to literally reinvent itself from the ground up. It is in a position to benefit from the good will of other nations by taking disaster and turning into fortune.
This is certainly not the time to allow religious factions to pound their chests and deceive the victims of a natural calamity by propounding on their own Freudian fears. Nor should shadowy merc units EVER step foot into this hellhole, KBR and it's ilk would latch onto the cash-flow going into this particular nation building and we'd never get any good done.
