Drought Leads To War.

[CapnAwesome]

If the Imperial Valley dries up the whole country will feel the effects on the supermarket shelves.

Considering almost all of imperial valley is well below sea level a moderate one time effort can ensure it stays quite wet permanently.

True enough, seems unlikely to lead to a civil war.

If Mexico was a real country, the wanton and sometimes total hijacking of water from Colorado river by the US, partly to water imperial valley, would have led to war.

Several major rivers in Asia, vital to the agricultures of India and Vietnam, originates from china. China is chronically short of water, and with global warming the situation is expected to get dramatically worse. To deal with this the Chinese intends to do on these rivers and to those countries exactly what the United States did on the Colorado river to Mexico, and has started major hydroelectric, aqueduct and irrigation projects that would reserve almost all water flowing in these rivers for use in china and all but stop all water from reaching down stream. This could very well collapse the agriculture in wide swaths of India and Vietnamese and lead to either war directly for water rights, or war nominally for other reasons but fundamentally with water rights as a major driving factor.

A lot of hypotheticals there (most of which have little to do with drought) and Mexico invading the United States wouldn't be a civil war. Besides, my original point was more one of wording than anything else. It's not the drought that causes war but the starvation.
