I wonder why no one has thought of that?
Please, you are either being intentionally naive or are just incredibly ignorant, if it is the former I would recommend doing a quick google search of the region's history. Whilst it would be great to live in a utopian world of global harmony this isn't the reality India lives in- on neighbour is engaging in a proxy war with India and destabilising the region and the other is growing more and more muscular everyday.
Heck, not even the "first world" presides over this peace you speak of- look at Europe (Ukraine), look at the Middle east where "first world" military forces are currently engaged. What do you think they are dropping from the air? Rainbows and daises or state of the art precision guided mentions?
