New York:
As part of efforts by the Pentagon to boost Pakistan's capability to take on Taliban and Al-Qaida militants, the US has stepped up military aid to boost Pakistani forces capability to strike in remote tribal areas, a development which could spark unease in New Delhi.
This comes after the Obama administration increased civilian aid to Pakistan last year.
The US will supply sophisticated laser-guided-bomb kits, 12 American-made surveillance drones and 18 late-model F-16 fighters jets to Pakistan.
All this, experts say, is to boost Pakistan's ability crack down on Taliban and Al-Qaida on the Pak-Afghan Border.
"You are rewarding good action so to say. Now we know that many Afghan Taliban have been arrested. Some say that seven of the 15 members of the Quetta Shura are under arrest. This is the way for the US to respond to that positively," says Dr Hassan Abbas of South Asia Institute, Columbia University.
Just a few months ago, the talk of increasing monetary and military aid to Pakistan created a furor in Congress with lawmakers questioning what action Pakistan has taken against militancy in return for US aid over the last decade.
But now as intelligence and military cooperation between the two has deepened, Pakistan is seen in the US as having taken strong steps in the campaign against terror.
Last week, Pentagon spokesman Geoff Morrell even praised Pakistan saying "The commitment that the Pakistani government, the military, its intelligence forces have demonstrated over the past several months to combating this threat within their midst is commendable. We are here to help them in any which way they are comfortable."
With this new arms aid, US counterinsurgency assistance fund for Pakistan is slated to double increase to $1.2 billion in 2011.
And of course, as has been the case in the past, the fear in New Delhi will be that US military aid given to Pakistan will be used to strengthen defenses against India.
