Let me offer an amateur analysis of your interrogative.

Since I haven't offered that you have said you were Japanese, other than my little witty reparte above,
you are volunteering the supposition that dishonesty is what is at question.

To my way of thinking, that's almost a confession of same.

More so in the beginning.. you posted with a Japanese flag,
used Japanese phrasing, ideology, axioms and nomenclature..
Even your avatar and nom-de-plume, Atom Boy, lent the impression, to any person with a brain, that you were a native Japanese, giving us the inside scoop on the catastrophe..
A bird's eye view, as it were.

You did and said NOTHING to dissuade that obviously mistaken categorization.

Very much a dishonorable act.
