Suppressing IS seems 'more realistic than destroying it'

Containing Islamic State may be a more realistic strategy than defeating it, a committee of British lawmakers said, calling on Britain to play a greater role in the fight against the militants in Iraq and Syria.

Britain has so far taken part in US-led airstrikes against the extremist group in Iraq, but not Syria. It has also provided some equipment and training for Kurdish forces.

Parliament's defense committee said in a report released on Thursday that these actions were "strikingly modest", with on average less than one airstrike a day, and said it was "surprised and deeply concerned" Britain was not doing more.
