NATO summit starts today

This is a good time to remind ourselves about what NATO is, because there's a summit underway in Wales starting today.  One of the big topics under discussion is the crisis in Ukraine.  There's a lot of history and complexity to these issues, but the conflict with Russia that's taking place right now definitely relates to the history and current dynamic between nuclear powers.  I'm still absorbing it, but I found this analysis and opinion piece from Salon interesting.
