Pakistan, India are militarizing their border. Basically, the dispute comes from India accusing the Pakistani ISI (their secret police) of orchestrating the terrorist attacks in Mumbai last month. Pakistan denies this, but it's unclear how much control Asif Ali Zadari, the current president of the country, has over the ISI anyway.
In the above link, it's explained that Pakistan is pulling troops off of the anti-Taliban effort on the Afghan border. It probably doesn't need explaining that a fourth war between India and Pakistan would be really, really bad.
