The United States is not to blame for the cross-border terrorism India faces today, and it did try to persuade Pakistan to stop the same, National Security Adviser Brajesh Mishra has said.

However, he also made it clear that asking New Delhi to resume Indo-Pak dialogue despite continued infiltration amounts to 'double standards' on terrorism.

"We cannot blame the US for the fact that cross-border terrorism has not ended. The blame lies somewhere else. But I repeat they did make sincere efforts in Islamabad and we are grateful for that. Cross-border terrorism continues and so, there can be no dialogue with Pakistan," Mishra said while briefing reporters on the talks he held with his US counterpart, Condoleezza Rice, US Secretary of State Colin Powell and other officials.

"You have to look at the issue from two different angles. One is whether the US and other governments did what they promised. The answer is, of course, they did. They did speak repeatedly to Islamabad about ending infiltration. So we cannot complain on that score."

However, Mishra said, Washington's efforts 'were not satisfactory from our point of view'.

"As far as double standards are concerned, there is a general plea that India and Pakistan should talk. How can we talk with cross-border terrorism still going on? So, when the US and other countries forget cross-border terrorism and urge us to talk, it amounts to double standards on the issue," Mishra said.

Mishra described as 'very satisfactory' the result of his discussions with Powell, saying this was because the US did not urge India to resume dialogue with Pakistan.

"The purpose of my visit to Washington was to renew my contacts, take a look at Indo-US relations, where they are headed, how they are developing and to talk about other issues which concern both,"  he said.

Asked about the triumph of the Islamic fundamentalists in the Pakistani elections in some parts, Mishra said the developing situation in Pakistan was discussed during his talks.

On the nexus between Pakistan and North Korean in developing nuclear weapons, Mishra said, "It is not (just) a bilateral issue between India and Pakistan." It concerns the entire world, he said.

When he goes to the Pentagon and meets with Deputy Defence Secretary Paul Wolfowitz, the two will talk about defence cooperation in general.
