Home Minister P Chidambaram says, he hopes that international opinion and its pressure combined with refusal to engage in a dialogue will force Pakistan to change its attitude towards terror groups operating from there. In an interview to a television channel he said, there have been several attempts by terrorists from across the border as well as modules within the country to launch terror attacks like 26/11 in India and these have been successfully foiled by the security agencies with better intelligence inputs. However, the Minister said, looking at Islamabad's attitude, India has strengthened its security manifold and is now better prepared in comparison to what it was an year ago.<br/>
