It was with far-sighted wisdom that the framers of our Constitution brought together in one magnificent phrase three great concepts—­“common defense,” “general welfare” and “domestic tranquility.”

More than a century and a half later we, who are here today, still believe with them that our best defense is the promotion of our general welfare and domestic tranquillity.

In previous messages to the Congress I have repeatedly warned that, whether we like it or not, the daily lives of American citizens will, of necessity, feel the shock of events on other continents.  This is no longer mere theory; because it has been definitely proved to us by the facts of yesterday and today.

To say that the domestic well-being of one hundred and thirty million Americans is deeply affected by the well-being or the ill-being of the populations of other nations is only to recognize in world affairs the truth that we all accept in home affairs.

If in any local unit—­a city, county, State or region—­low standards of living are permitted to continue, the level of the civilization of the entire nation will be pulled downward.

The identical principle extends to the rest of the civilized world.  But there are those who wishfully insist, in innocence or ignorance or both, that the United States of America as a self-contained unit can live happily and prosperously, its future secure, inside a high wall of isolation while, outside, the rest of Civilization and the commerce and culture of mankind are shattered.

I can understand the feelings of those who warn the nation that they will never again consent to the sending of American youth to fight on the soil of Europe.  But, as I remember, nobody has asked them to consent—­for nobody expects such an undertaking.

The overwhelming majority of our fellow citizens do not abandon in the slightest their hope and their expectation that the United States will not become involved in military participation in these wars.

I can also understand the wishfulness of those who oversimplify the whole situation by repeating that all we have to do is to mind our own business and keep the nation out of war.  But there is a vast difference between keeping out of war and pretending that this war is none of our business.

We do not have to go to war with other nations, but at least we can strive with other nations to encourage the kind of peace that will lighten the troubles of the world, and by so doing help our own nation as well.

I ask that all of us everywhere think things through with the single aim of how best to serve the future of our own nation.  I do not mean merely its future relationship with the outside world.  I mean its domestic future as well—­the work, the security, the prosperity, the happiness, the life of all the boys and girls in the United States, as they are inevitably affected by such world relationships.  For it becomes clearer and clearer that the future world will be a shabby and dangerous place to live in—­yes, even for Americans to live in—­if it is ruled by force in the hands of a few.
