WASHINGTON - A senior State Department spokesman Friday deflected a series of questions about how the Obama Administration would react if the Pakistan government imposed martial law in NWFP where a military offensive was ongoing, saying he wasn't aware of any such move. On his part, US Assistant Secretary Philip Crowley told a news briefing that the United States commended the "aggressive action" Pakistan was taking to deal with extremism within its borders. "There is an aggressive military action occurring in Pakistan to deal with these issues. How the Pakistani military decides to engage in this fight is really a matter for the Pakistani military and the Pakistani Government," he said. "We are working aggressively to support Pakistan in this effort, and we are focused in particular on the current situation regarding displaced persons in Pakistan, but those kinds of decisions are, in fact, up to the Government of Pakistan." When insisted that there were reports that Pakistan might impose martial in parts of the country, Crowley said, "I am not aware of these reports. Obviously, as Ambassador (Richard) Holbrooke said earlier this week, Pakistan is taking aggressive action to deal with extremism within its borders, and we commend them for it. But we are focused primarily on the plight of the 2.5 million refugees or displaced persons, and we're trying to work as hard as we can to help Pakistan in any way possible. QUESTION: So can you try to address the question, though, which is whether you would have any misgivings about the Pakistani Government ... CROWLEY: Well, I mean to - I understand. QUESTION: Can I finish my question, please? I mean, it's a reasonable question. There is a long history of marital law being declared in Pakistan, a lot of interest among the Pakistani population in the US Government working with multiple military leaders; you have no misgivings whatsoever about the idea of the martial law being declared in parts of Pakistan? CROWLEY: First of all, I am not aware of - I am aware of what you're suggesting. I am not aware, in particular, of these reports. But I - we understand that there is an extraordinary situation going on in Pakistan. There is an aggressive military action occurring in Pakistan to deal with these issues. How the Pakistani military decides to engage in this fight is really a matter for the Pakistani military and the Pakistani Government. We are working aggressively to support Pakistan in this effort, and we are focused in particular on the current situation regarding displaced persons in Pakistan, but those kinds of decisions are, in fact, up to the Government of Pakistan.
