Did Bush threaten Pakistan?

We know that when Pakistani PM Gilani visited Washington, the US "presented evidence" of ties between the ISI and Taleban, but what was left unreported was, to what degree, there was a backside threat.

This is from a Pakistani paper, so judge for yourself, but it seems to imply a pretty menacing, if vague, threat in the conversation.

President George W Bush confronted Yusuf Raza Gilani in Washington last week with evidence of involvement by the ISI in a deadly attack on the Afghan capital and warned of retaliation if it continues.....

Gilani, on his first official US visit since being elected in February, was left in no doubt that the Bush administration had lost patience with the ISIís alleged double game. Bush warned that if one more attack in Afghanistan or elsewhere were traced back to Pakistan, he would have to take 'serious action'.
