A. P. J. Abdul Kalam vs Abdelaziz Bouteflika

Kalam led the development of India's first indigenous satellite launch vehicle (SLV-3) under the SLV-3 project at ISRO. The first experimental flight of SLV-3 in 1979 failed, but the second in 1980 successfully placed the Rohini satellite in orbit, making India a spacefaring nation.

As Chief Scientific Adviser to the Defence Minister, Kalam played a key role in India's second nuclear weapons test at Pokhran. The tests established India as a nuclear weapons state, leading to international sanctions but also strategic autonomy.

Kalam published his autobiography 'Wings of Fire', detailing his early life, work at ISRO and DRDO, and his role in India's space and missile programs. The book became a bestseller and inspired millions of young Indians to pursue science and public service.

Kalam was elected as the 11th President of India with support from both the ruling NDA and opposition parties. He served a single term from 2002 to 2007, becoming known as the 'People's President' for his accessibility and focus on youth and education.

Bouteflika was elected president after all other candidates withdrew, citing fraud. His election aimed to end the Algerian Civil War, and he quickly pursued a policy of national reconciliation.

Bouteflika's government passed a charter offering amnesty to Islamist militants who laid down arms, effectively ending the Algerian Civil War. The charter was approved by referendum and led to a significant reduction in violence, though it was criticized for impunity.

Bouteflika, despite being in poor health and rarely appearing in public, won a fourth presidential term. The election was marred by low turnout and allegations of fraud, fueling public discontent that later erupted in the Hirak movement.

After months of massive weekly protests known as the Hirak movement, Bouteflika resigned from the presidency. The protests demanded an end to his rule and the dismantling of the political system that had kept him in power for 20 years.
