Well I do not know what Nationalism exactly this meme is referring to.
But the National Socialist party has been the only political ideology able to protect a nation from the Jewish "Socialism"
Before the Jews managed to separate the 2, National and Social where one and the same.
While Jewish Socialism is international and thus strive to destroy all nations and create a one world government.
That is why and how the National Socialists choose their name with care.
Americans are insane and retarded.
What do you think when Americans look you in the eye and say Indonesia and Laos are the same country?
Yon can't feeling hopeless when Americans say the USA never bombed Iraq before 2001.
You know that the US is doomed when Americans say Biden supporting wars, debt, and tyranny was wrong, but Trump loving wars, debt, and the police state is just fine.
