Very doubtful. The Russians have all they can handle just hanging on to the remaining little not-quite-Russia bits of Russia, such as Chechnya. They’re not even going to try to take back the Ukraine, never mind Poland.
Chechnya is all but gone through a series of agreements that have resulted in greater de facto autonomy for the region. Ethnic Russians are receding and other peoples are moving in. This is the natural order of things. The Nation-State has created the false problem of containing people in territorial borders even while others recede naturally.
This sentence does not mean anything.
Yes, it was poorly phrased.
What I meant was, even while other demographic populations recede naturally. Like Russia has territory ripe to be moved into by populations nearby that are overcrowded and in the past they simply would have migrated into the new territory, but now because of national boundaries that’s more problematic.
the export of which precious commodity is going to bankroll the existence of the majestic unified Arab empire on that map 100 years from now? AFAIK the only significant industrial powers in the neighborhood now are Israel, Iran and Turkey. And, unsurprisingly, these are also the dominant powers of the region, possibly with the addition of Egypt (at least when they can secure enough foreign aid, like in 1973). Iraq also had its good moments, but for now it seems headed straight into the Iranian hands.
