It's about time they do, but to actually predict their next move is beyond me. NATO is doing everything they can to communicate with Russia. In a report that dates back to 6 days ago, U.S. Air Force Gen. Philip Breedlove confirmed that NATO is in the process of re-establishing "direct contact" with the chief of the Russian general staff, Gen. Valery Gerasimov. Let's see how things go. This is a war where you can't let weapons do all the talking.
I think the possibility of a NATO intervention is quite unlikely but i wouldn't be surprised to see aid coming from individual countries that want to support Ukraine. That is of course assuming that Ukraine don't join NATO in the near future.
