War only brings destruction and is good for neither country, in fact China does everything they can to stoke division between these two nations because it keeps rival region powers weak. I'd say that India and Pakistan are culturally quite similar, but get involved in petty disputes that occasionally blow up in a spectacular way. Any time war happens, especially between two nuclear powers, it is likely to create a bit of a dip in the markets as investors try to determine whether to reallocate their portfolios away from a danger zone. Keeping a strong economy is actually a good reason not to go to war, Russia is in the middle of it's invasion right now and has lowered itself so many rungs down the economic ladder, they can paint a rosy picture by producing tanks (that get destroyed rather quickly) in a war economy, but it doesn't actually add value and eventually drains all reserves.
