It’s more important to worry about your own matters. Yes believers should show concern for world affairs, but remember:
1- We have a lord who is managing the entire universe and he has a plan. Don’t worry too much.
2- We have an Imam. Imam Mahdi. Through him Allah will take care of things.
So don’t worry too much and rest assured that Allah is seeing everything and while the enemies plan, He plans too, and he is the best of planners.
