It is a start.
But why the hell are we selling an enemy advanced weaponry in the first place, much less giving them money to help pay for it?

The Pakis are given money to pay for weaponry, so that they can use their own money to buy Chinese weaponry. America makes China rich in more ways than one!
Military aid to the Pakistanis started long before Obama.
