Hours after US President Joe Biden's comment that India is an exception among Washington's allies with its "shaky" response to the Russian invasion of Ukraine, a top American official has said democracies need to "stand together and evolve their position". President Biden yesterday made the comment while praising the US-led alliance, including NATO, the European Union and key Asian partners, for a united front against Russian President Vladimir Putin. But in the Quad - comprising India, Australia, Japan and US - India continues to buy Russian oil and has abstained from votes condemning Moscow at the UN.
