John J. Maresca is a retired US Ambassador, whose career has spanned decades of diplomatic service and conflict mediation. Born in Italy, he arrived in the US as an infant with his American mother, on the last ship leaving Europe as World War II was beginning. After serving as a US Naval officer, he embarked on a successful career as a diplomat, serving as the Chief of Staff for two Secretaries General of NATO. From that position, he began negotiating with the USSR in Helsinki in 1972. He was the central American official and Ambassador in the long set of negotiations aimed at closing the Cold War between East and West in Europe, through the final summit-level all-European signature session in Paris in 1990. He was then named as the Special US Ambassadorial Envoy to ceremonially open direct US diplomatic relations with each of the "newly independent States from the former USSR," following the break-up of the USSR. He traveled to each of those new states on that mission, starting with the newly-independent Ukraine. He then became a roving American conflict mediator, seeking to resolve local conflicts in Cyprus, Nagorno-Karabakh, and regions of former Yugoslavia, before retiring from the US diplomatic service. He subsequently became Vice President of the Unocal Corporation (now a part of Chevron), focusing on regions of conflict including Afghanistan and the Caucasus. He has published several books and numerous articles, and has spoken on conflict issues in more than sixty countries, on every continent except Australia.
