Rapid development has led to stark differences within that country, parts are modern, affluent, well-educated...and they live shoulder to shoulder with tribal, impoverished, and practically primal apes. It's the same issues every country faces when rapid development comes their way. It's going to be incredibly challenging for them to develop a healthy middle-class and egalitarian society.
It's more likely that the rapid modernization just leads to increased concentration of power to an oligarchy, and exploitation of the most vulnerable. Also fascist tendencies are all the rage these days on the international stage, of course those in power are looking on with interest.

In a sense, war is mostly logistics. It doesn't matter how strong your unit is, how clever you tactics are, or brilliant your strategy is. None of those things matter if the unit is not where they need to be, with the supplies to be effective.
Most countries have limited ability to project military force outside their country because the logistics become so hard to support. Russian military relies heavily on rail transport, which doesn't extend into Ukraine anymore, and trucks what it can't rail...but the supply depots need to be hundreds of km behind the line because of long range precision missile strikes. With long supply chains supported to heavily stretched trucking, guys at the front won't get everything they want.
