"This is SO funny!!!
And you are so confused and ignorant. What is "opposite" about Nationalism and Socialism? Can you spell "Nazionalsocialismus"? Probably not., but even you can probably spell the familiar shortened version "Nazi".
Nationalism and Socialism are two philosophies at opposite ends of the ideological spectrum. Hitler was able to attract both ex-communist workers and their industrialist bosses, by playing both sides off against each other. Hitler's Nationalism emphasized supreme loyalty to the nation and the race, what we'd call patriotism, and the errosion to that effect of personal liberties. At the same time, he appealed to the Left by promising full employment and a redistribution of wealth. The Leftist side of the equation was more or less dropped after the 1934 Night of the Long Knives, by which time he had destroyed the Left and now needed to attract the full support of the middle classes. Certainly by the start of the Second World War, Hitler's Nazism was all Nationalism and no Socialism.
