"This demand will come parallel to US demands for same action and, and threats by incoming US President Barack Obama to force greater cooperation from Pakistan," says Strategic Forecasting (Stratfor).

It is not clear, Stratfor says, the degree to which the Pakistani government can control the situation.

"But the Indians will have no choice but to be assertive, and the United States will move along the same line. Whether it is the current government in India that reacts, or one that succeeds doesn't matter. Either way, India is under enormous pressure to respond," it adds.

Therefore, the events point to a serious crisis not simply between Pakistan and India, but within Pakistan as well, with the government caught between foreign powers and domestic realities. Given the circumstances, massive destabilisation is possible, it says.

In an analysis, it says that in the current situation, the demands will be even more intense. The Indians and Americans will have a joint interest in forcing the Pakistani government to act decisively and immediately. Pakistan, Stratfor's analysis notes, has warned that such pressure could destabilise Pakistan.
