What is the most likely reason that italy and germany supported the nationalists in the spanish civil war?

Italy and Germany also had nationalistic governments, and there were a lot of similarities among them. With nationalists winning, Germany and Italy had allies in Europe, and a counter-balance to Great Britain and France. Also, they believed that this could stop the spread of communism to other parts of Europe. Strategically, a nationalistic government was a benefit for the German and Italian regimes of the time. 

SO, a economic and political partnership if it help u plz pick as best tncx
