It's tough to say. Gotta probably ask the Indians. In fact, I actually think that if they had played conservatively for 20 overs and then took things on, they might have chased it. They have the hitting power later to even score 100 off the last 10 easy peasy.
They definitely underestimated Pakistan that day; there was this telling moment for me in the second or third ball that Kohli faced off Amir before he knicked the first one. He played it back to Amir, who took it and mock-threw it towards the batsman's stumps. Kohli was just smiling looking at him like 'why the drama bro', almost casually while Amir looked like Kohli had slapped him mom. The intensity difference was stark. Don't think India countenanced the kind of Pakistan that turned up that day; a polar opposite of the meek version that almost looked at the Indian stars in awe over the past few meetings. It was great to see that fire that tells me that India-Pakistan contests are now back on even-keel after a period in which we just made up the numbers simply because of our attitudes.
I guess that's the shift from Dhoni to Kohli. Dhoni would have chosen to take the game deep, Kohli looks to dominate. It's great when it comes off, but there was a reason India rarely got humiliated very often under Dhoni. He was a percentage master who would back himself to take it to a quasi-impossible situation and then hold his nerve. That's why what happened in the IPL today was truly vintage.
Anyways sorry I went on a tangent but felt that was an illustrative point.
