Tee is referring to the bogus nonexistent attack by the North Vietnamese on the Maddox and the Turner Joy in the Gulf of Tonkin.
It is most probable that the Korean ship was fired upon by a North Korean submarine, and that this was a message to the South that North Korea was unhappy with the end of the "sunshine policy" of the previous S. Korean government.
If this has not caused a war yet, I deem it unlikely that one will result. No one can actually win a war. The South would suffer serious damage to Seoul, the North would end up with a deposed government, and the war would trigger financial crashes on the markets. China would be most unhappy, because they do not want N Korean refugees, and there would be unpleasant problems even for the Russians and the Japanese. It would be seriously imbecilic for any of the parties to actually start a war. There might be some more foolish INCIDENTS though.
