This is a list of hostile incidents at the Argentine border.
This timeline does not include events from the 1982 Falklands War, nor the 1978 peak of the Beagle crisis with Chile.
It should be note that Argentina's use of force against Chile and the United Kingdom has been the exception rather than the rule, and some of the hostile acts or armed incidents appear to have been caused by zealous local commanders, and not as the result of a widespread strategy.
[1] Most of the naval incidents involve illegal fishing boats predating squids and fish species outside exploitation seasons and allowed seizing by the Argentine law in Argentine Exclusive Economic Zone waters.
