It's very easy to judge RAM. I can be very good in that also... But the point stands - other country wouldn't do [ask for help] it with a case like a nuclear sub. But let me make it more clear - US wouldn't ask russia and russia wouldn't ask US! Yuo want an example? Right now, the Discovery shuttle is in danger but there's no way the US would ask for any help - why? Pride of their national space program may be? Up to you to judge on that, but I'm not impressed with how it's being handled... If someone wants to kid themselves about the end of cold war, I'm not- at least about its new form - both countries still consider themselves as potential enemeis when you scratch the surfaces. Of course - it's about the governments - the oil driven war-waging american, and the superpower-complex russian.
The people would always get along just fine.
Russians handled the Kursk situation miserably, but from every source I've read - the 118 (or 119, but not 150) people that died in Kursk had very little chance since the 9th compartment escape hatch was damaged and wouldn't allow the hollywood type docking with a rescue sub. There were 23 or so people there after the explosion, and their fate no doubt was awful. Either way, I hope those 7 crewman get rescuewed but it's a bit strange to see people getting impression that Russia changed some approach to handlng such situations. It's just totally different scale of the event, and they'd always react in similar way to this type of event. Just like if there's another major event with a nuclear sub - they are unlikely to ask for help.
ALl the secret stuff we don't care about - they do. And it's been like that for years, and will stay that way as well.
