On the one hand, the world is intrigued by India's new leader, Narendra Modi, who inflicted such a devastating defeat on the grand old party of Indian politics and has replaced the well-known and widely respected Manmohan Singh.

On the other hand, the world is anxious about the foreign policy implications of someone who has held no national post and will lead the government of a billion-strong, nuclear-armed country with the world's fourth-biggest economy in purchasing power parity ($5.4 trillion to Japan's $4.7 trillion).

The world should stop worrying. The elements of foreign policy continuity under the Bharatiya Janata Party (BJP) and Congress-led governments of AtalBihari Vajpayee (1999-2004) and Manmohan Singh (2004-2014) are far more numerous and substantial than the readjustments on the margins.
