Strength and wisdom are not opposing values.

The line asserts that effective leadership (or moral character) does not require choosing between being forceful and being thoughtful. “Strength” can mean resolve, courage, or the capacity to act; “wisdom” suggests judgment, restraint, and learning from experience. By denying that they are “opposing values,” the speaker rejects a common political dichotomy in which toughness is portrayed as incompatible with nuance or deliberation. The claim implies that the best decisions join power with prudence—strength guided by wisdom—rather than substituting bravado for insight or caution for capability.
