The future wars would be fought on the basis of who has the best intelligence on targets, on human targets.
This involves on the one side observation (SIGINT), and on the other side elicitation of information (HUMINT). Observation would be done by nanobots which can fly, penetrate spaces semi-autonomously and can observe those spaces, can record speech, can read, can download data from other data stores, etc. and can relay all that elsewhere for data crunching by artificial intelligence servers which can correlate information, filter the relevant information and present it to human analysts.
Just consider, someone sitting in Delhi Intelligence Central would know everything that is being planned, discussed in all of Pakistan, who is saying what, who he is, where he is.
If needed, he could finish off anybody he pleases by pressing a single button, upon which another nanobot could inject him with some poison and make his death look completely natural. If he wishes he can kill off 300 million Pakis with a single button. That is the power of nanotech. But the idea is to be able to target others far more precisely and at a time of one's choosing. With the technology one can shut off a Qaddafi or a Saddam Hussein any minute.
The other part of technology would involve something like Fringe Shapeshifters who can be made to look like and to act like anybody one wants.
We could exchange Kiyani with our own shapeshifter and Mrs. Kiyani would not know about it.
