It depends upon what the meaning of the word ‘interventionalism’ is. If ‘interventionalism’ means any intervention over Ukraine of any kind, that is one thing. If it means there should be no military intervention or aid in Ukraine, I agree with you.
So, you apparently don’t asupprt arming them (the McCainiac position) which I don’t asupport.
But, do you support NGO’s, mercs, and what some have said took place - US AID working in Ukraine.
Do you support the last three?
