While the claim is detailed, the specific phrasing ('We know exactly how the military balance of power stands. We know it is not in our favour, but we also know that our population is ready to accept the principle of putting the country's interests before anything else.') appears to be derived from a single context or source summary, although the general theme is present across multiple web results. Without a direct cross-reference confirming this exact quote from multiple independent outlets, it cannot be marked 'corroborated'.
