I kept wondering why we (human) don't go back to the Quran and Sunnah of the Prophet. Allah in His infinite wisdom created all human from one man and woman and make us one race which is the race of human. He made us look black or white out of His supreme wisdom for easy identification for us.
Then I wonder why we (humans) have created artificial divisions among ourselves in colour, tribe, race and ethnic lines.
These divisions creation has definitely led us into the inhuman mess we are right now. Almost in every countries of the world today, you see divisions along either race or tribe or ethnic and it has been a basis for self inflicting conflicts and war. Yet we pray to the Almighty to save us from the self inflicting conflicts we created with our own hands.
The Prophet said Allah is never interested in our look (colour, beauty etc) nor in our wealth (riches, knowledge) rather His interest lies in our heart (faith, intention) and our deeds.
Why then do we base our judgements of dealing with fellow humans based on colour or tribe when indeed our creator Who knows all shows no interest in it.
The earlier we go back into the words of Allah and the Sunnah of the Prophet the better our world. The peace we seek is never an impossible thing for Allah to do but we have to change our ways before Allah restores peace in this world because He said in His holy book that "Verily! Allah will not change the good condition of a people as long as they do not change their state of goodness themselves (by committing sins and by being ungrateful and disobedient to Allah)." Q 13 V 11.

^Really, you have a sound and noble thought but the reality is that our Lord Himself created us into different nations and tribes but with a purpose:

O mankind! We created you from a single (pair) of a male and a female, and made you into nations and tribes, that you may know each other. Verily the most honoured of you in the sight of Allah is the most conscious (of Him). And Allah has full knowledge and is well acquainted (with all things). {surah Hujurat: 13}

It is very necessary that mankind is re-structured into various color, shapes and languages. Apart from these being among the signs of Allah which we are to reflect upon, its a test to determine who will submit to Allah the creator by lowering one's pride and ego of superiority due to race. The holy prophet of Islam (peace and blessing be upon him and his household) warned against social and racial discrimination in various ahadith. The view of muslim should be:

Respect your fellow human either as your brother in faith or your equal in humanity {Imam Ali ibn Abi talib (alaih Salam)}

It doesn't matter whether the mother is non-muslim and doesn't matter if the child is born through illegal intimacy, the man still have the full responsibility on him. He should seek for Allah's forgiveness of his committed sins and work righteously and most importantly guide the child to the ways of Allah.
