Why would it spill over? There are many countries who renounce russia and the war did not spill over to them. Neither are people dying in these countries because of that.

Sure india has many benefits from russia and it is kinda obvious that the indians only want what is best for them. But efforts are made to help india and strengthen relationships so they can condemn this genocide and atrocities. They do not need to send weapons. The first step would be to tell russia and the world that what russia is doing should stop and retreat. Actualy not that big of a deal for them. Russia needs india to buy their stuff.

Actualy many countries did that and did not have any disadvantages despite condeming them. Russia is still trading with them.
