Take a look at a map of NATO. Now take a look at a map of EU aid to Ukraine. The only real non-NATO members of the EU are, what? Ireland, Switzerland, Austria, and Serbia (and a few microstates)?
Oh, would you look at that! Guess who hasn’t been providing significant military aid to Ukraine. No guns and no ammunition. (In other news, even China has provided Ukraine with humanitarian aid…)
This is a proxy war between the US and Russia. The only significant aid from non-NATO states has been from, what, Pakistan (who oppose anything India supports lol), Australia (who are otherwise aligned with the US through ANZUS/AUKUS), Israel (do I even need to say anything?), and Japan (who are obviously aligned with the US)?
