What a week it has been! While Prime Minister Narendra Modi has been lauded for pushing the Indo-US relationship to new heights, the Gandhis received a shock, with long-term 'loyalist' Jayanthi Natarajan raising the banner of rebellion and accusing the Gandhis of 'interfering' in her ministerial work. So what will be the impact of the revolt? Will the Gandhis find it difficult to maintain their 'iron grip' over the party? While PM Modi has been steadfastly moving away from Nehruvian ideas in the realm of foreign policy, President Obama's presence during the Republic Day parade has been a diplomatic coup. So will the Indo-US relationship go beyond the 'personal chemistry' between the two leaders or will the geopolitical irritants still persist?
