A gross oversimplification of what happened here. Nation states do not seize the uninformed members of each other military in international waters. That is a violent breach of International Law. It is a gross oversimplification to compare this to arresting a drug smuggler or a drunk tourist.
If you clicked on the link I provided on incidents during the Cold War, you will see that not only were uniformed members seized, they were killed in violation of international law. And international law is a thin reed to base anything on.
"In 1988 U.S. warships sank an Iranian frigate and shelled two Persian Gulf oil platforms near the Strait of Hormuz in response to a mine attack against the USS Samuel B. Roberts, an American frigate. A few months later, the U.S. Navy accidentally shot down an Iranian commercial jet carrying 290 passengers and crew. The American government mistook the plane for a military fighter jet but refused to apologize or admit any wrongdoing."
