Twitter wars: US launches social media offensive against Islamic State

The United States has launched a social media offensive against the Islamic State and Al-Qaeda, setting out to win the war of ideas by ridiculing the militants with a mixture of blunt language and sarcasm.
Diplomats and experts are the first to admit that the digital blitz being waged on Twitter, Facebook and Youtube will never be a panacea to combat the jihadists.
But US officials see social media as an increasingly crucial battlefield as they aim to turn young minds in the Muslim world against groups like IS and Al-Qaeda.
For the past 18 months, US officials have targeted dozens of social network accounts linked to Islamic radicals, posting comments, photos and videos and often engaging in tit-fot-tat exchanges with those which challenge America.
A senior US State Department official described the strategy as a kind of cyber guerilla campaign.
