Precisely because we are willing to bear its burden, we know well the cost of war. And that is why we built an alliance that was strong enough to defend this continent while deterring our enemies. At its core, NATO is rooted in the simple concept of Article Five: that no NATO nation will have to fend on its own; that allies will stand by one another, always. And for six decades, NATO has been the most successful alliance in human history.

Suppose aliens invade the earth and threaten to obliterate it in a year's time unless human beings can find the Ramsey number for red five and blue five. We could marshal the world's best minds and fastest computers, and within a year we could probably calculate the value. If the aliens demanded the Ramsey number for red six and blue six, however, we would have no choice but to launch a preemptive attack.
Paul Erdős
The moral faculties are generally esteemed, and with justice, as of higher value than the intellectual powers. But we should always bear in mind that the activity of the mind in vividly recalling past impressions is one of the fundamental though secondary bases of conscience. This fact affords the strongest argument for educating and stimulating in all possible ways the intellectual faculties of every human being.

Generally, the officers of the army were indifferent whether the annexation was consummated or not; but not so all of them. For myself, I was bitterly opposed to the measure, and to this day, regard the war, which resulted, as one of the most unjust ever waged by a stronger against a weaker nation. It was an instance of a republic following the bad example of European monarchies, in not considering justice in their desire to acquire additional territory.

The permanent revolution, in the sense which Marx attached to this concept, means a revolution which makes no compromise with any single form of class rule, which does not stop at the democratic stage, which goes over to socialist measures and to war against reaction from without that is, a revolution whose every successive stage is rooted in the preceding one and which can end only in complete liquidation.

For any exam in history, here is the answer: all human history is the struggle between systems that attempt to shackle the human personality in the name of some intangible good on the one hand and systems that enable and expand the scope of human personality in the pursuit of extremely tangible aims. The American system is the most successful in the world because it harmonizes best with the aims and longings of human personality while allowing the best protection to other personalities.
