I am sorry to hear about this situation. Quora contributors retain ownership over content they contribute, but, someone in your situation will likely not be able to get a retraction. Or rather, it may not be practical. Allow me to explain why.
1) Despite what some people say, there is no international copyright law. There is copyright laws in each country, and then treaties and agreements between multiple countries to recognize and give credit and enforce copyright laws of each partner country. India and USA do have a copyright agreement to recognize and enforce each other's copyright, but -
2) The problem is India's legal system. You can sue in USA and then try to enforce the judgment as foreign judgment in India. OR, you can sue in India directly. Either way, India's legal system is notoriously slow and overwhelmed. It would literally take years and thousands of dollars to enforce this. Ergo, pursuing this in Court is not or may not be a practical step to take.
3) Someone in your situation can write a letter threatening to sue - or have a local Indian attorney do so - and perhaps the newspaper will be scared enough to retract this.
Please note: If I tell you simply what you wish to hear, this would be unfair to you. I need to be honest with you and sometimes this means providing information that is not optimal. Negative ratings are reserved for experts who are rude or for erroneous information. Please rate me on the quality of my information; do not punish me for my honesty.
I hope this helps and clarifies. Please use the SEND or REPLY button to keep chatting, or please RATE when finished. You may always ask follow ups at no charge after rating. Kindly rate my answer as one of TOP THREE FACES/STARS and then SUBMIT, as this is how experts get credit for our time. Rating my answer the bottom two faces/stars (or failing to submit the rating) does not give me credit and reflects poorly on me, even if my answer is correct. I work very hard to formulate an informative and honest answer for you; please reciprocate my good faith with a positive rating.
