Parallelism is the name we give to the organization of ideas and expressions of identical structure. We have two types of parallelism: the syntactic parallelism, related to the terms of the same syntactic structure within a sentence; already the semantic parallelism, related to the similar ideas within a phrase.
The text presented in the question shows through several phrases that the nation will do anything to ensure the survival and success of freedom. These sentences are related to similar ideas within the text and this represents the Semantic Parallelism.
