The law of France enacted in January last, which subjects to capture and condemnation neutral vessels and their cargoes if any portion of the latter are of British fabric or produce, although the entire property belong to neutrals, instead of being rescinded has lately received a confirmation by the failure of a proposition for its repeal. While this law, which, is an unequivocal act of war on the commerce of the nations it attacks, continues in force those nations can see in the French Government only a power regardless of their essential rights, of their independence and sovereignty; and if they possess the means they can reconcile nothing with their interest and honor but a firm resistance. Hitherto, therefore, nothing is discoverable in the conduct of France which ought to change or relax our measures of defense. On the contrary, to extend and invigorate them is our true policy. We have no reason to regret that these measures have been thus far adopted and pursued, and in proportion as we enlarge our view of the portentous and incalculable situation of Europe we shall discover new and cogent motives for the full development of our energies and resources. But in demonstrating by our conduct that we do not fear war in the necessary protection of our rights and honor we shall give no room to infer that we abandon the desire of peace. An efficient preparation for war can alone insure peace. It is peace that we have uniformly and perseveringly cultivated, and harmony between us and France may be restored at her option. But to send another minister without more determinate assurances that he would be received would be an act of humiliation to which the United States ought not to submit. It must therefore be left with France (if she is indeed desirous of accommodation) to take the requisite steps. The United States will steadily observe the maxims by which they have hitherto been governed. They will respect the sacred rights of embassy; and with a sincere disposition on the part of France to desist from hostility, to make reparation for the injuries heretofore inflicted on our commerce, and to do justice in future, there will be no obstacle to the restoration of a friendly intercourse. In making to you this declaration I give a pledge to France and the world that the Executive authority of this country still adheres to the humane and pacific policy which has invariably governed its proceedings, in conformity with the wishes of the other branches of the Government and of the people of the United States. But considering the late manifestations of her policy toward foreign nations, I deem it a duty deliberately and solemnly to declare my opinion that whether we negotiate with her or not, vigorous preparations for war will be alike indispensable. These alone will give to us an equal treaty and insure its observance.
