Hamas V. PLO

The irony in the ongoing conflict is that Hamas, whose founding members were encouraged by Israel in the 1970s and 80s against Yasser Arafat’s secular national movement, has turned out to be Israel’s biggest rival in the Palestinian territories. HAMAS Hamas was established after the first intifada broke out in 1987, as an offshoot of the Egyptian Muslim Brotherhood.  Intifada was the Palestinian uprising against Israeli occupation of the West Bank and Gaza Strip.  The first intifada lasted from 1987 to 1993, and the second began in 2000.

The statue of Swami Vivekananda at the JNU campus

 Prime Minister Narendra Modi virtually unveiled a life-sized statue of Swami Vivekananda at the Jawaharlal Nehru University (JNU) campus on November 12. JNUSU (JNU students' union), un response, planned to protest on campus.  They believe the Modi government “openly supported” violence on campuses and is attacking universities with the National Education Policy which will result in fund cuts and privatization of education. FUNDING CONTROVERSY It was on June 30, 2017 that JNU’s Executive Council (EC) first gave approval for the statue.  The administration said it was installing the statue to give the campus a more “pleasing look” as Vivekananda had contributed to “nation building”. The administration remained mum on who was funding the statue and how much it would cost.  Then JNU Students’ Union president N Sai Balaji filed several RTIs to know about the funding. In January 2018, he filed an RTI seeking the total cost of construction of the statue as well as the sour...
