I think the liberal left in the West are having some difficulty or catching up to do and need some time to decide who the good guys and bad guys are.
Of course the liberal left will ultimately want to support Pakistan, being the relatively militarily weaker, economically smaller and less populous of the two countries. The point of who started the conflict is irrelevant to the liberal left.
However another challenge is that there are no Jews involved, it wouldn't necessarily be a problem to replace the words "Jew and Zionist" with "Hindu and Hindutva " except that Indians inconveniently have "brown faces" which could open up accusations of racism which the liberal left really don't want.
So you have to appreciate that it's all terribly difficult for the liberal left to process at the moment. They will get there eventually in their support of Pakistan but it will take time.
That said in order to help the liberal left speed up their decision on picking the "oppressed " side to support it would be incredibly helpful if Indians especially in the UK could please temporarily wear some "white face" to make it clearer to the liberal left that they are "the bad guys".
Many thanks
