"For many years McCain held Kerry's actions
against him because, while McCain was a POW in
the Hanoi Hilton, Kerry was organizing veterans
back home in the U.S. to protest the war."
"In his 2002 book, "Man of the People: The Life
of John McCain," Alexander says that the two
Vietnam vets finally reconciled in the early
1990s after having "a long - and at times
emotional - conversation about Vietnam" during a
mutual trip to Kuwait.
"Later, Kerry sought to minimize the rift,
telling Alexander: "Our differences occurred
when we were kids, or at least close to being
kids. It was a long time ago, and we both came
back and realized that there were a lot of
difficulties in the prosecution of that war." "
