After Paris attacks, pressure builds for big military response to Islamic State

WASHINGTON (Reuters) - The Paris terror attacks are likely to galvanise a stronger global military response to Islamic State, after a U.S.-led air war that has lasted more than a year has failed to contain a group now proving itself to be a growing worldwide threat.

    The United States, long accused of taking an incremental approach to the struggle, is under growing political pressure at home and abroad to do more and it is expected to examine ways to intensify the campaign, including through expanded air power.
