Indian leaders rushed to praise Barack Obama on his US presidential triumph, but analysts warn that policy changes under his administration could "irritate" what has become a key strategic relationship. Obama's election as the first black US president was hailed by Prime Minister Manmohan Singh on Wednesday as an "extraordinary" journey that would "inspire people not only in your country but also around the world." Singh noted the current strength of US-India relations, which have been cemented under outgoing President George W. Bush, and said he looked forward to working with Obama to realise the "enormous potential" for bilateral cooperation. However, analysts here voiced concerns that an Obama presidency would bring new pressures. "We have to see whether the old Democratic attitude towards India will resurface," said Arundhati Ghosh, former Indian envoy to the Geneva-based Conference on Disarmament. She was referring to earlier Democratic administrations that berated India on its human rights record in Kashmir and pressured New Delhi to accept US mediation to resolve the dispute over the divided region that has caused two wars between India and Pakistan."If this happens, the comfort one had developed with the Bush administration will evaporate," Ghosh said. "As I see it, Kashmir and (trade) protectionism are two big problem areas." Under Bush, relations warmed considerably, with Washington adopting a hands-off approach on Kashmir and leaning on Islamabad to end support for an Islamic insurgency in the region.
