What is one focus that is similar between communist and socialist platforms?

The main similarity of Socialism and Communism is that their main economic philosophies that are advocated are that public rather than private ownership of the means of production, distribution, and exchange of goods. The government is the one that regulates the production of goods and there is no regulation of prices by the market, instead, the prices are all regulated by the government.

Japan was expansionist, imperialist and mostly run by the military.

In Germany, we see the rise of the Nazi Party, which gained its first minister in 1930.

Soviet Union was a huge communist country. Which means that everything in the country belonged to the government.

In Spain, Primo de Rivera was forced to resign in 1930 and the King, Alfonso XIII, called for elections to be held in a democratic fashion, opening a way to the Second Republic
