Conquering land is no longer necessary since capital has global mobility and is usually no longer tied to any particular location. Even before there is a slight chance of a territory becoming unstable, there will be capital fright and thus all incentive for waging war in the first place will have been snuffed out. Modern capital (on industrial scale) is extremely risk averse, hence seeing so little foreign investment into unstable countries and territories and capital following the path of least resistance - from least stable to most stable. It's why Saudi and Russia are investing hundreds billions into foreign markets and not the other way around.
