nice fiction
Things change, & already are changing!
1) there will be no army coup, whatever they're doing they're doing so by staying in the background, so, all of your hypothetical assumption is discredited on the first point. Army has changed it's strategy with respect to political dealings. These are just wishful thinkings i've been hearing since years. good luck with your rhetoric of "failed state" lol
2) unstable country? lol you should visit Syria, or Iraq or South Sudan to understand the definition of "unstable country".
3) FYI FDI is going to be at the highest in coming years! Russia & central Asian countries are going to invest in energy projects, then Pakistan is going to give them the opportunity to use Gawadar! All of these are Multi-billion prospects for Pakistan & work has already been started! & I haven't even Included the projects by China. lol This is what has been itching Indian Govt, this economic prospect alone would belittle the Indian economy, India can never have the kind of strategic importance Pakistan has.
don't know what kind of political or strategic studies you've been doing, i guess you need to stop reading fictional digests
