When Bonaparte was to be dethroned, the Sovereigns of Europe called up their people to their aid; they invoked them in the sacred names of Freedom an… - Henry Temple, 3rd Viscount Palmerston

[I]f this opium had been seized in the ordinary course of Chinese authority, as being a contraband article, brought into China against the law—if it had been seized by the Chinese authorities within Chinese jurisdiction, there would have been no claim on the finance or upon the power of this Government to demand compensation or redress from the Government of China. It was entirely owing to the manner in which the opium had been extorted, that the late Government had felt that an outrage upon British subjects had been committed, which not only authorised but rendered necessary measures of hostility, should such be required. It had been said that what the late Government demanded was satisfaction for the injured honour of the country, and that one of the ways in which satisfaction was to be given was payment for the opium so extorted.

The hon. Member for Manchester (Mr. Bright) asks, "What is our interest in this war?" and he also asked me to explain the meaning of the expression "the balance of power." ...[The] "Balance of power" means only this—that a number of weaker States may unite to prevent a stronger one from acquiring a power which should be dangerous to them, and which should overthrow their independence, their liberty, and their freedom of action. It is the doctrine of self-preservation. It is the doctrine of self-defence, with the simple qualification that it is combined with sagacity and with forethought, and an endeavour to prevent imminent danger before it comes thundering at your doors.

The honourable gentleman has alluded to the distresses and financial embarrassments of the country. I should be the last man to speak of those distresses in a slighting manner; but in considering the amount of our burdens, we ought not to forget under what circumstances those difficulties have been incurred. Engaged in an arduous struggle, single-handed and unaided, not only against all the powers of Europe, but with the confederated forces of the civilized world, our object was not merely military glory—not the temptation of territorial acquisition—not even what might be considered a more justifiable object, the assertion of violated rights and the vindication of national honour; but we were contending for our very existence as an independent nation. When the political horizon was thus clouded, when no human foresight could point out from what quarter relief was to be expected, when the utmost effort of national energy was not to despair, I would put to the honourable gentleman whether, if at that period it could have been shown that Europe might be delivered from its thraldom, but that this contingent must be purchased at the price of a long and patient endurance of our domestic burdens, we should not have accepted the conditions with gratitude? I lament as deeply as the honourable gentleman the burdens of the country; but it should be recollected that they were the price which we had agreed to pay for our freedom and independence.
