Introduction
The term just war [justum bellum or iustum bellum] refers to both a kind of deliberative moral doctrine and corresponding ethical theory/s to justify the doctrine itself. In both cases, however, the term can be ambiguous, insofar as one does not distinguish its related normative and descriptive functions. Take care to distinguish these. It is especially important to also distinguish using the doctrine to make standardized judgements about the justice of undertaking a particular war [jus ad bellum or ius ad bellum] and the rules that should govern the conduct of a war [jus in bello or ius in bello] once the conflict begins. Hence one can make a four-fold and cross-cutting distinction between a justifiable war and one that is not, on the one hand, and justifiable [or not!] conduct of a war, on the other. And so there can be justifiable wars, according to the theory/s, that are conducted justly or not and unjustifiable wars that are conducted justly or not.
Accordingly it is not always a straightforward matter to say that a war is immoral [or not]! Better to ask if the potential or actual war itself is permissible or not [or even obligatory or not!] and then go on to ask of particular warfare strategies & tactics if they are, in turn, permissible or not [or even obligatory or not!].
Furthermore you can and should ask whether or not the articulation or exposition and rational justification of a just war doctrine or a just war theory is cogent, especially with respect to more general ethical theories, e.g., utilitarianism(s), deontology(s), natural law morality(s), virtue morality(s), etc.
SEARCH SITES & WEB DIRECTORIES
Using lower case characters, search on the exact phrases - just war; just war doctrine; just war theory.
You can usually do this directly by placing "double quotes" around each exact phrase in the search window. Make sure you leave a space between each search term. If this does not work, follow the search site's Advanced Search directions.
Advice: Open each "hit" in a new window using the right click button on your pointer. That way you can compare sources side-by-side. It's not very efficient to be "clicking" back-&-forth.
Next do a more focused search using the topic phrase/s in various combinations with the following [lower case] exact phrases & single words.
Using the Advanced Search function, also try searching on the .edu and .ac domains; these will get you to academic sites, which are usually rich resources. Note: While the .edu domian designation can be used alone, the .ac domain designation must be used in combination with a nation domain designation, as in .ac.uk (united kingdom) or .ac.au (australia).
Finally: Using the Advanced Search function, do searches for .pdf / .doc / .rtf files. These will often net you substantial essays & extensive class notes. Of course, the caveats especially apply here.
