effects in Mexico. One would be to drive the price of oil skyward. Even if less is produced, the revenues would increase. If we do the nasty in Iran, expect a round-up of large numbers of undocumented inside the U.S., 75% of whom are Mexicans. The militarization of the border is a sure bet.
The forced reentry of millions of Mexicans would undoubtedly have a destabilizing effect. The overthrow of the current bogus Administration in Mexico City is almost inevitable, as would be some effort by the Bush-Cheney regime -- ruling by emergency decree from national command center in Colorado after the loss of Washington and several other major American cities -- to replace it with a military junta.
All these scenarios seem so much more credible than they were just a year or two ago. See
Children of Men, imagine Mexico as the refugee camp by the sea -- that captured it very well.
