Cryptography, the art of writing and solving codes, is essential for national security in our increasingly digital age. Governments use sophisticated cryptographic techniques to protect sensitive information, such as military strategies, diplomatic communications, and intelligence data, from unauthorized access. Without strong cryptography, nations would be vulnerable to espionage, sabotage, and other threats that could compromise their safety and well-being.

One well-known example of cryptography's role in national security is the Enigma machine used by Germany during World War II. This complex device scrambled messages, making them virtually unreadable without the correct decryption key. The Allies' success in breaking the Enigma code, thanks to the brilliant work of mathematicians and codebreakers at Bletchley Park, significantly aided their war effort and shortened the conflict.

Today, cryptography plays an even greater role in protecting national security as nations grapple with the challenges of cybersecurity. Governments rely on advanced encryption algorithms to secure their computer systems, networks, and critical infrastructure from cyberattacks. They also use digital signatures to verify the authenticity of electronic documents and communications, ensuring that they have not been tampered with.

Furthermore, cryptography is crucial for securing the technologies that underpin national security, such as satellite communications, military drones, and missile defense systems. By encrypting data transmitted by these systems, governments can prevent adversaries from intercepting and exploiting sensitive information that could compromise national security. As technology advances, the importance of cryptography in safeguarding national security will only continue to grow.

The World Health Organization (WHO), a specialized agency of the United Nations, plays a crucial role in promoting global health and well-being. [I] This guiding principle calls for international cooperation to address health challenges that transcend national borders. [II] From eradicating smallpox to combating HIV/AIDS and working to contain Ebola outbreaks, the WHO has been instrumental in tackling some of the most pressing health crises of our time. [III] Its efforts extend beyond responding to immediate emergencies; the organization also works proactively to strengthen health systems, promote research, and set global health standards. [IV]

The WHO's work is guided by its six core functions. These include providing leadership on matters critical to health and engaging in partnerships where joint action is needed; shaping the research agenda and disseminating valuable knowledge; setting norms and standards and promoting and monitoring their implementation; articulating ethical and evidence-based policy options; providing technical support to countries and building sustainable institutional capacity; and monitoring the health situation and assessing health trends. Through these multifaceted approaches, the WHO strives to achieve its overarching goal of “Health for All,” ensuring that everyone, regardless of their background or location, has access to quality healthcare services.

The WHO also plays a vital role in coordinating international responses to public-health emergencies. During the COVID-19 pandemic, for instance, the organization worked tirelessly to provide guidance to countries, track the spread of the virus, and accelerate the development of vaccines and treatments. The WHO's leadership in declaring the pandemic and disseminating vital information proved crucial in mobilizing global resources and coordinating efforts to mitigate the impact of the virus. Similarly, the organization has played a key role in responding to other infectious disease outbreaks, including Ebola and Zika, highlighting the importance of its role as a global health coordinator.

From its headquarters in Geneva, Switzerland, the WHO works through six regional offices and 150 country offices, collaborating with governments, non-governmental organizations, and other partners. By bringing together diverse stakeholders, fostering collaboration, and championing evidence-based approaches, the WHO strives to improve health outcomes worldwide and create a healthier, more equitable future for all.
