I changed the former introductory phrase ("Ion Victor Antonescu was a Romanian soldier, authoritarian politician and convicted war criminal.') for the following reasons:

 the fact that he was a soldier is not the most important from his CV. According to Britannica: "Ion Antonescu,  (born June 15, 1882, Pitești, Rom.—died June 1, 1946, near Jilava), Romanian marshal and statesman who became dictator of the pro-German government during World War II."

 in my opinion the reference to his execution for war crimes does not belong to the first sentence (see other articles about war crimininals: Albert Wass, Constantin Petrovicescu, Visarion Puiu)
