For two nations that say they want to avoid escalation, India and Pakistan seem trapped in a dangerously spiraling conflict.

India¡¯s strikes on Pakistan and Pakistan-controlled Kashmir Wednesday were clearly telegraphed ¡ª a fitting answer, it believes, for last month¡¯s terror attack in Kashmir. In response, Islamabad claims it has shot down five of New Delhi¡¯s aircraft. Civilians are now dead on both sides.

Avoiding any further intensification is critical for these nuclear-armed states. Keeping diplomatic channels open is crucial, too. The alternative is a cycle of counterstrikes that risks dangerous missteps.
