New Delhi: The US is aggressively pressing Pakistan to curb terrorism and the proposal to attack Iraq is part of the strategy to focus on one country at a time in the ongoing fight against the menace, US Senator Sam Brownback said on December 13.

Asked about Indian concerns on the US adopting double standards by treating Pakistan on a different pedestal while dealing with terrorism, he said it is a sequential war in which all countries cannot be dealt with in one go.

"We are pressing Pakistan aggressively on terrorism, I called up President Musharraf when there was a danger of confrontation with India and told him he has to control cross-border infiltration," he said while addressing an industry gathering.

"There should not be an obsession with Pakistan in this country. I am now going to China, not Pakistan," he said.

The world has benefited by engaging Afghanistan which was a destabilising force in the region and in the "sequential war", focus has now to be on Iraq as not only does it have terrorists on its soil but is involved in making chemical, biological and nuclear weapons, he added.
