Dr Jones is an archaelogist like his father before him... I can't see a archaelogy relation to the Cold War? Maybe the Russians are looking for Atlantis to buff up their Navy when the Nazis failed? Too far-fetched and none were as fanatic as the Nazis in relgious artifacts... I read that Mel Gibson is seriously discussing with Director George Miller about reprising his Mad Max role. I can see Harrison Ford as an old Indy reprising his role too but if we are looking for an actor to play his other adventures same age as in ROTLA or TTOD then it has to be someone else. I grew up with Ford as Solo and Indy too but we need an actor to fit the story not a story to fit the actor. BTW, Mel Gibson didnt want the MM4 offer originally but now is changing his mind!
