Ok first of all.
Todays terrorists may be tomorrows Nations.
That's an age-old truism.

With that out of the way :)
Let's look at developing western war theory / technologies.
Specifically American.

The needs.
1. No more body bags (extremly unpopular at home, those body-bags)
2. More time efficient and non-subjective information.
3. pinpointing/isolating and taking out specific goals/targets.

Problems with it.

1. A lot of countries will find it as examples of extremly 'cowards warfare'.
Especially those still being in 'feudalistic development' Bosnia/Serbia and 'third world/development Countries as Somalia etc.

2. It will create more of '7/11 solutions' as that will be the terrorists primary possibility of getting a 'payback' delivered.

3. Considering how widespread nuclear, chemical and biological technology is nowadays this seems as a rather disquieting option.

4. No exact guarantee that what you take out really will be the correct target and/or produce the right result, as you've limited 'humint' (HUMan INTelligence)

Conclusion.

That should mean that those countries implementing this kind of warfare in the end will find themselves forced to implement a 'police-state'.
And that every terrorist action / insurgence will produce even stricter enforcements regulating the individuals 'democratic rights'.

So who will this benefit?
