The bomb attacks certainly points towards the commies for their diversion technique, when each and every person in India is blaming them for their role of trying to hijack the nation in the interest of the Chinese in the nuclear deal. With rock-bottoming popularity they had no other option than to harm the country again for their short term mean self interest, this time through SIMI, which has strong base in West Bengal (many a times with covert state government support) and UP. Hence the repeated post (parliament) poll meeting of Karat with Mayavati, to formulate the strike targets and methods? These commies can do anything for even slightest of their interest as the killing fields of Campuchia, the Bamboo Gulags of Korea or the Siberian and Chinese concentration camps showed over the decades. All fingers points to this.
