In the NY Times two days ago:

President Bush has decided to send an unusually tough message to one of his most important allies, President Pervez Musharraf of Pakistan, warning him that the newly Democratic Congress could cut aid to his country unless his forces became far more aggressive in hunting down operatives with Al Qaeda, senior administration officials say.

Democrats, who took control of Congress last month, have urged the White House to put greater pressure on Pakistan because of statements from American commanders that units based in Pakistan that are linked to the Taliban, Afghanistan’s ousted rulers, are increasing their attacks into Afghanistan.

So it looks like the new get-tough-with-Pakistan stance is really in response to pressure from Democrats. GW threatens Musharraf with a warning that the new Congress may seek to cut aid to Pakistan -- again, the new Congress, not GW himself. And Democrats have been urging Bush to pressure Pakistan based on "statements from American commanders," as if Bush didn't hear those same statements.

But you'll hear the right-wingnuts applaud these sudden get-tough actions towards Pakistan as if it was all GW/Cheney's doing.... Just more uninformed assumptions.
