The battle to secure India’s most vulnerable strategic corridor has officially begun. The Siliguri Corridor — India’s famous Chicken’s Neck — is just 22 kilometres wide at its narrowest point and connects over 50 million people in the northeast to the rest of the country. Now, after a key political shift in West Bengal, New Delhi is rapidly pushing ahead with fencing, surveillance systems and deportation drives under a massive Smart Border initiative. Amit Shah has promised a complete crackdown on infiltration and demographic manipulation along India’s eastern frontier. But this comes amid growing concerns over China’s footprint in Bangladesh, Pakistan-Bangladesh defence ties and strategic pressure building around the corridor itself. India’s eastern security calculus is changing rapidly. The question now is whether Delhi can secure the Chicken’s Neck without triggering bigger regional tensions around it.
