If the war will not escalate that much like the big countries will not participate in their war if it will happen then we have nothing to worry about it. Though it can effect the oil price but I am sure that big countries will find a way in order to either limit the damage of their war or put a sanction to their countries so they will be force to stop the war.

But let's just hope that it will not happen so we can live a peaceful life especially that we are currently facing a pandemic as of this moment, it will be a big burden if war will follow even if the pandemic is still there.
