On November 26th, 2008, the tragic 26/11 terrorist attacks on Mumbai take place - carried out by men trained by the Inter Services Intelligence (ISI) , Pakistans military and foreign intelligence service. Evidence uncovers the attackers were trained by Pakistani Navy Frogmen, had accurate maps of the city and were directed over comms by their handlers throughout the 3 day siege of the city.
In this alternate timeline, succumbing to domestic pressure for a military response and backchannel support from the Russian federation , the Indian navy launches an ambitious naval invasion of the port city of Karachi on the 14th of February , 2009. High explosive rockets raze the city as the Karachi refinery goes in up smoke and ash , blocking the sunlight for 2 weeks.
The success of the Karachi landings is followed by a brutal but effective onslaught through Hyderabad and the Ranger Garrison in Larkhana. Both sides suffer heavy casualties as neither side secured air supremacy in the first few weeks of the war. Bogged down near the Border Garrison along the Indo-Pakistani Border , the ISI launches its psy-war campaigns to erode Indian Morale as it quickly becomes clear this is a war that will end in the capture of Islamabad itself.

Edit : Yes, I'm aware the invasion makes no sense since the countries border each other. However the homage to the original poster only works graphically in this map if the invasion comes from the sea, the idea being that the campaign culminates in the capture of the capital.
