You mean, Colin Powell, the man who lied to the United Nations in order to start a war that killed hundreds of thousands of innocent people? The man who never apologized for this, and merely said this:

"Of course I regret that a lot of it turned out be wrong," he said. In an unbroadcast interview for Frontline in May 2016, Powell said, "at the time I made the speech [to the UN]...the President [George W. Bush] had already made this decision for military action."[7]

No apology. No admission of any guilt at all, completely casts the blame.

Hundreds of thousands of innocents were murdered because of his words.

You mean Colin Powell, the war criminal? Why should decent humans have to listen to such a monster?
