The correct answer is "provide for the common defence."
According to the Preamble of the U.S Constitution, the aforementioned part about providing for the common defence actually means that the nation should be well prepared against foreign interventions of any kind.
This kind of preparation does not only refer to military preparation but also refers to protecting the country at any costs from external forces.
A consequentialist approach to ethics is an approach that claims that the morality of an action depends on its outcome. This means that an action is "good" is the consequence it brings is good as well. An example of such a theory is Utilitarianism. Utilitarianism states that an action is morally good if it leads to the most happiness for greatest number of people. However, an objection that can be made to this theory is that utility and happiness are subjective, as well as difficult to measure.
On the other hand, non-consequentialist ethics state that the morality of an action is based on the rightness and wrongness of the actions themselves and not the consequences of those actions. An example of this is the Natural Rights Theory, which states that humans have an inherent right to certain rights, regardless of human behaviour. However, it is unclear who has the right to state what these rights are, which has led to criticism of the theory.
