RandiRona is understandable. India diplomatically invested a lot (dance around naked) on US in last decade to lure them away from Pakistan. There umpteen head of state meetings in G7, G20, QUAD have one important agenda to somehow isolate Pakistan from US forever. Further, Indian lobby in US congress is very strong too and amongst the best. Compares to it Pakistani PM got hardly and rare such chances. With so much investment and continuous back-biting about Pakistan into american ears they thought they have owned US now and will kill any goodwill in US circles before it try to surface leave out materialising.
But, alas as usual Pak-US works silently until its done. The Shock of this deal is heart wrenching in indian circles, they could not pre-empt it..... how that it could be? that's the main grievances of India to US on this deal at the moment
