Parts One and Two of Tequila Junction describe the assault by a foreign nation on the Americas. While this assault has had politics as its objective, it has supported itself through local commodity trading (mostly in drugs). That makes it a well-veiled variant of 4th-Generation Warfare (that which is fought in the political, economic, psychological, and martial arenas simultaneously. Undermining this attack before it can too drastically affect the heartland will take deploying lone U.S. infantry squads to Combined Action Platoons (those shared with host-country police and soldiers) and patrol bases in Colombia, Panama, and possibly even Mexico. Part Three has the unconventional warfare techniques those U.S. squads will need to survive many times their number of drug traffickers and narco-insurgents. Those techniques have been derived from the counterinsurgency methods of the Vietnamese, Chinese, Japanese, and Iranians (those armies with the most cultural predisposition toward 4GW). This heavily illustrated book discusses events as recent as July 2008. Only by closely following its proposals will the U.S. counterinsurgency effort have much chance in either the Americas or Afghanistan.
