We don't care if Pakistan aids Ukraine militarily because their aid can't change anything and Russia knows it too.If India purchased from US, French, and Israeli suppliers and excluded Russian suppliers I do not think it would change the military balance between India and Pakistan.
If Pakistan stopped supplying Ukraine and gave China the opportunity to offer something in exchange (this is an important reciprocal part of my suggestion) then it would help Russia on the battlefield.
I'm sorry to say this but I think you're just trying to find an excuse and are the 4th Pakistani commentator to ignore concerns.
