It is even more so, as nations do not respond to the impulse of self-sacrifice.

With national safety as the primary object to be attained in territorial settlements, the factors of the problem assume generally, though not always, the following order of importance: the strategic, to which is closely allied the geographic and historic; the economic, affecting the commercial and industrial life of a nation; and lastly the ethnic, including in the terms such conditions as consanguinity, common language, and similar social and religious institutions.
The national safety and the economic welfare of the United States were at stake in the War of Secession, although the attempt to secede resulted from institutional rather than ethnic causes.

The same was true when in the Papineau Rebellion of 1837 the French inhabitants of the Province of Lower Canada attempted for ethnic reasons to free themselves from British sovereignty.

Had the right of "self-determination" in the latter case been recognized as "imperative" by Great Britain, the national life and economic growth of Canada would have been strangled because the lines of communication and the commercial routes to the Atlantic seaboard would have been across an alien state.

The future of Canada, with its vast undeveloped resources, its very life as a British colony, depended upon denying the right of "self-determination." It was denied and the French inhabitants of Quebec were forced against their will to accept British sovereignty.
Experience has already demonstrated the unwisdom of having given currency to the phrase "self-determination." As the expression of an actual right, the application of which is universal and invariable, the phrase has been repudiated or at least violated by many of the terms of the treaties which brought to an end the World War.
