::Well, I genuinely believe discussing is never useless. It is the core of the partecipative effort.  
 ::However, I can only be happy to have more eyes on this article. Indeed, the issue is that for too long time this article has been basically the "land" of one single editot. Concerning comments from other users, Cyclopia, you are already the second administrator aknowledging that my edits are correctly sourced (the first after a 3O). 
 ::But, for the avoidance of doubt let's put the sources in the context. This is the edit (I have extended it to verbatim copy from the sources and exclude any allegation of misrepresentation and also because 4 sources can well support three lines of text):  

 ::A second wave left at the end of the war with the beginning of killings, expropriation and other forms of pressure from the Yugoslavs authorities to achieve control. In 1945 in Rijeka the liberators carried out a series of public murders and instituted an intense policy of Croatization of the city. by January 1946, more than 20,000 people had left the province. 

 ::The description of what happened during the second wave of the exodus is perfectly in the context. Get convinced by yourselves: 
 ::1)Ethnic Cleansing and the European Union - Page 136, Lynn Tesser - It contains the exact sentence of the proposed edit. The full paragraphs says: They left in several waves, first following Italy's capitulation in fall 1943 and the departure of collaborators with the fascist regime. Terrifying air raids in Zadar troughout 1944 also led half of the city's residents to flee to Italy. a second wave left at the end of the war with the beginning of killings, expropriation and other forms of pressure from the Yugoslav authorities in their campaign to achieve control..  
 ::2)History in Exile: Memory and Identity at the Borders of the Balkans - Pamela Ballinger, Princetown University Press, UK, 2003 - Page 77 - It contains the following sentence about the second period of the exodus  A second wave followed at war's end as Yugoslavs used force and intimidation to install the facto control. The full paragraphs says almost the same thing: The first wave abandoned Istria in 1943 when the collapse of the Italian regime and army left vulnerable those individuals most compromised with the fascist state (including officials sent from other parts of Italy, especially the south); a second wave followed at war's end, as the Yugoslavs used force and intimidation to install de facto control.. 
 ::3)People on the move: forced population movements in Europe after WWII and its aftermath - Pertti Ahonen et al., Berg, USA, 2008 - Page 106 - The exodus from Rijeka/Fiume  started in 1945 and had place during the second wave of the exodus: In Rijeka the liberators carried out a series of public murders and instituted an intense policy of Croatization of the city..  
 ::4)Literary and Social Diasporas - Gerry Turcotte, G. Rando, Belgium, 2007 - Page 174 - Concerning the events of 1945 in Rijeka/Fiume the book says: On the night of 2 and 3 May 1945, Fiume was occupied by vanguards of the Yugoslav Army. Here more than 500 collaborators, Italian military and public servants, as well as anti-Fascists and innocent people were summarily tried and executed. By January 1946, more than 20,000 people had left the province.''. This very same book starts the paragraph with the description of what happened in Zadar. 

 ::Now, I am happy to see Direktor's sources stating an alternative version. Otherwise the edit is legitimate and should be published. Pleaae mind that in the article there are not many sections so well sourced. In particular there is an entire section about the Julian March under the Fascism without a single, decent, English source.
