The march of hundreds of Central American migrants through Mexico has inflamed tensions between the Trump administration and the Mexican government and focused attention on the United States' southern border.
The ostensible reasons for the march are familiar: The migrants were fleeing corruption, social and political turmoil, and lack of opportunity in their home countries. Many were from Honduras which suffered a coup in 2009 that continues to divide the country politically including during the last election in which supporters of the challenger to the incumbent president claim their candidate was cheated out of a win.
All of this reminded me of Jean Raspail's novel The Camp of the Saints. In it, impoverished Indians seized hundreds of ships docked in their harbors and set sail to find a better place to live. (The book was published in 1973 when many believed that millions of Indians and other Asians would likely starve in the coming decades due to poor agricultural yields. The full effects of the so-called Green Revolution still lay ahead.)
