This is great--let the goodwill triumph all the time. Regardless of my overall negative view of Putin, in this case he did a right thing. It would be great if rescuers from Russia, Europe and other places will be invited to participate in the rescue effort. America is always ready to help whenever disaster strikes no matter what the political relations with the affected country.
I'll be really surprised if any of the main EU nations send anyone. The Germans are busy reading us lectures rather then offerring help.
