Solution for each and every problem of humanity only and only lies in unity, peace, progress and prosperity of humanity as a proper human community in a kingdom. This is the only way mankind could have blissful, dignified and secure existence.
This is what the quran offers humanity in form of way of life labelled AL-ISLAAM. If anyone has any better idea then one should share it with rest of humanity but none has any better idea so far. Then why not be a sensible human being and accept what is true and right and give up what is false and wrong in order to save mankind from yet more terrible painful suffering due to harms and destructions by hands of each other?
It is most beneficial for people who are suffering in terrible pain and agony to take this message aboard and spread it to wake up sleeping humanity to this truth. Even if they are not bothered with learning and teaching proper deen of islam then humanity does deserve what it is getting as consequences of its thoughts and actions.
People make each other suffer terribly then blame it on God that he is not intervening whereas God has already intervened by providing people with his guidance but people are ignoring that guidance and looking for solutions elsewhere which are not there.
