Invasions by both sides, across the US - Canadian border, very much like the "Iranian violation of Sovereignty" described, occur about weekly during salmon fishing season in the northwest. ...

There seems to be some significant difference of opinion between the two countries as to what consitutes "territorial waters," but the problems generally get resolved (after the season ends) as "a little disagreement between friends."
