Concerns and supporting positions
Alternative positions and responses
Ganges water treaty renewal
Concerns and supporting positions
Bihar’s ruling National Democratic Alliance is opposing renewal of the India-Bangladesh Ganges Water Sharing Treaty as its 30-year term approaches expiry.
Alternative positions and responses
The treaty’s stated purpose is to provide predictable dry-season sharing of Ganga waters between India and Bangladesh; Bangladesh has previously experienced reduced downstream flows and related water and ecological stresses.
Proposed H-1B fee
Concerns and supporting positions
The US Department of Homeland Security is seeking another route to impose a large additional fee on annual-cap H-1B petitions after a federal court struck down the administration’s earlier US$100,000 charge.
Alternative positions and responses
The H-1B programme allows US employers to hire highly educated foreign professionals for specialty occupations, and India was the largest beneficiary of approved applications in 2024, with 71%.
Lake Ontario renaming
Concerns and supporting positions
US President Donald Trump signed an executive order directing the United States to refer to Lake Ontario as “Lake America,” describing it as a US national asset.
Alternative positions and responses
Canadian Prime Minister Mark Carney said “Ontario” comes from the Indigenous Wendat people; the US order does not determine what Canada or the rest of the world calls the lake.
