A subordinate clause, or dependent clause, will begin with a subordinate conjunction or relative pronoun, so as to join the clause with the main sentence, because they cannot stand alone. It will also contain both subject and predicate. Taking this into account, the subordinate clause is:

B) Which was erected to guard the harbor.

but it does not cost our pride. it does not cost the guilt that would arise from knowing that we did nothing to intervene while our neighboring nations fell to despotic leaders.

it does not cost the terror of knowing that our allies are unstable. it does not cost the fear that we, too, will be next to fall.
