He will blame Russia for Taliban.
He will blame US for Iraq.
He will blame Israel for Hamas.
He will blame India for Kashmir conflict.
He will blame infighting among Rajputs for Mughal invasions.
He will blame Babri demolition for peaceful terrorism in India.
He will blame Gandhi-Nehru-Savarkar for partition of India.
He will blame Satan for Shia-Sunni conflict.
