Also notice how Putin is targeting civilian areas in his assault - he didn't expect so much resistance, both in war and in the propaganda efforts, so he became desperate and began bombing civilian buildings. Safe to say Ukraine is gone.
''Safe to say that Ukraine is gone'' - you killed whole nation by making such sentence. Be careful by making such bald statements.
But I agree that USA didn't gave significant help. Even from sanctions for Russia perspective - sanctions that they imposed is such soft compared with what EU countries have done.
