^^ major concern would be safety of 8-9millions indian expats in the gulf. Increase in crude oil prices could increase our import bill as we are heavily dependent on energy, which means $$ reserves could take some hit, if it's 1-2 week affair then it won't pinch much because we have 70-75 days of reserves in oil. Supply lines and logistics are also taking some heat, this could be a problem as well.
From geo political pov, meh we are used to walking on tight ropes.
I guess there is atleast half a dozen Indian were killed in those attack but governments are not reporting anything to avoid the panic and the picture of safest countries in the world but middle east will not be safe anymore I guess.
Iran got enough resources to retaliate for a month atleast if I am not wrong, so we should be prepared for what's to come.
And taking the side with US on this matter might affect the relationship with Russia too.
