The National Review: Kevin D. Williamson: 'FDR's Nationalism Presaged Donald Trump's'

Source:The National Review- "President Franklin Roosevelt delivers a fireside chat from the White House, 1933 (National Archives)" President Franklin D. Roosevelt (Democrat, New York) 32nd President of the United States.

"Professor Samuel H. Beer of Harvard, once a speechwriter for Franklin Roosevelt, lived nearly a century, from 1911 to 2007. If he’d lived a bit longer, he might have made a good speechwriter for Donald Trump."

From The National Review

I don't want to sound like I'm trying to offend, but Kevin Williamson's who I tend to respect at least politically, has nationalism and progressivism, mixed up with a what I call unitarianism and not the religion, but in governmental sense.

The United States unlike the United Kingdom and like the Federal Republic of Germany is a federal republic. We have decentralization of governmental power in America. We have checks and balances, as well as branches of government. National, state, and local, and in many cases Americans tend to live under two local government's. County and city and if you live in the City of Los Angeles, or in Chicago (to use as examples) you know exactly what's that life. Since the City of Los Angeles is part of Los Angeles County and Chicago is part of Cook County.

In a country that has a unitarian government or is a unitarian state like Britain, most of the governmental power, but not all is centralized with the national government in London. 

The U.K. Government runs the education system for Britain, as well as health care and health insurance for the entire country. Whereas in America each state even city, county has their own public education system and make their own governmental decisions for all other local matters that go on in their local jurisdiction and state.

President Franklin Roosevelt, was neither a Nationalist or a Unitarian when it came to government policy. The man led us along with our allies through World War II and saved the European Jews from ethnic destruction from the German Nazis. 

If FDR was a Nationalist, we would've stayed out of Europe and perhaps Japan as well, especially if he were truly a Democratic Socialist who didn't believe in government force and a strong military during World War II.

According to Wikipedia

"Nationalism is a political, social and economic system characterized by the promotion of the interests of a particular nation, especially with the aim of gaining and maintaining sovereignty (self-governance) over the homeland. The political ideology of nationalism holds that a nation should govern themselves, free from outside interference and is linked to the concept of self-determination. Nationalism is further oriented towards developing and maintaining a national identity based on shared, social characteristics, such as culture and language, religion and politics, and a belief in a common ancestry.[1][2] Nationalism, therefore, seeks to preserve a nation's culture, by way of pride in national achievements, and is closely linked to patriotism, which, in some cases, includes the belief that the nation should control the country's government and the means of production."

President Franklin Roosevelt, was a Progressive in the true sense of the term. Someone who believed in progress and that progress could obtained through government action. That government could be used to promote and achieve progress in the country. 

FDR inherited the Great Depression and believed government should be used to help Americans through the Great Depression with things like Unemployment Insurance and Social Security, but that government could also be used to help us get out of the Great Depression and back to strong economy health. 

Pre-New Deal, there was no public safety net or a national infrastructure system of any kind and with President Roosevelt we saw the Federal Government pay for the financing of American roads and other infrastructure projects in America.

If FDR was a Unitarian or Socialist, he would've nationalized the public education system in and all public welfare policy would be complete run by the Federal Government. No more local public hospitals, because now the Feds would be running those hospitals, as well as public housing, no more private health insurance.

Under FDR the Federal Government got a lot bigger and spent more money than it did before especially as it related to the economy, but our National Security State was also created under FDR and we became a world economic, military, and diplomatic power under FDR. Because he was a liberal internationalist who believed in a strong America both at home and abroad. 

Democratic Socialists, who tend to be very dovish on foreign policy and national security. FDR, was a Progressive Democrat in the truest and best sense of the word, he did put limits on what government should do and try to do and who also believed in individual success in America.
