Quote by Calvin Coolidge
No nation ever had an army large enough to guarantee it against attack in time of peace, or ensure it of victory in time of war.
Summary
This quote suggests that no matter how powerful or large an army a nation possesses, it can never guarantee complete protection against attacks during peacetime. Likewise, even a massive army cannot ensure victory during times of war. This implies that relying solely on military might is not sufficient for security or success, highlighting the importance of other diplomatic, political, and peace-seeking measures to foster lasting security and prosperity for a nation.
