In a daring and internationally reported event, Radlovic helped organize a group of fellow fugitives from the Naval Base at Kotor after the German carpet bombing of the capital of Belgrade.
They fled for freedom on board the British built Hrabri-class submarine named Nebojša (Fearless) during the German bombing invasion of April, 1941.
After a treacherous journey, endangered by Axis bombing (at one point his family heard radio reports that the submarine was missing and believed sunk), he arrived in Alexandria, Egypt.
Serving with the famous "Desert Rats", commanded by General Bernard Montgomery, Radlovic participated in many battles (such as Tobruk, El Alamein and Monte Cassino) throughout North Africa and Italy.
After Reuters he then founded the influential publication European Affairs where he worked closely with Bertrand Russell and George Bernard Shaw.
In the late 1950s, Radlovic went back to Yugoslavia to recommence legal studies at the University of Belgrade, where, in 1959, he met another student, Milena Djukic, who became his wife.
He founded Pomona Realty Co., which grew to encompass 16 offices, and United Business Brokers, both located in the Inland Empire of Southern California.
In his later years, even after he became seriously ill, he worked on a project to build a World Trade Center near the Ontario International Airport, which never reached fruition.
Longtime friends California State Senator Jim Brulte of Rancho Cucamonga and L.A. County Supervisor Mike Antonovich led their respective elected bodies in adjourning in Monte Radlovic's memory upon the day of his death in August 2000.
