Quote from bearice:
Do you think Russia will help after what USA did during Soviet Union's invasion of Afghanistan.
I do.
By giving up the missile defense sites in Europe we are allowing Russia to keep a gun to Europe's head. That allows Russia to bully everyone in Europe over natural gas prices/supply and lots of other issues they like having hegemony over. Also some afghans were showing up in the fight in Georgia. They don't mind seeing some taliban killed.
I wouldn't be surprised if they helped us with Afghanistan or Iran for that matter. I notice they haven't gone ahead with the planned sale of advanced SAMs to Tehran so perhaps they are giving us a little help.
