I'm sorry but I don't think you understand the argument, the history, and why statements like the bolded one are utterly ridiculous. In fact, I can say -with absolute certainty - based on the times we've done it before that a sustained bombing campaign is more likely to persuade rather than dissuade people to join IS.
Similarly, I don't understand why you're calling an unwillingness to jump headfirst into doing what we always do 'sitting and twiddling your thumbs'. Its that hawkish, warmongering, attitude, that sees us sleep walk into these crisis. No one (not even Corbyn, although your so keen to say otherwise) advocates doing nothing, you're confusing calls for a sensible, managed, considered response, one which shows evidence of having learnt from our mistakes in the past, with a hand washing 'not our problem' response.
So far our response to the IS attacks in Paris has been exactly what IS wants. In 2001 our response to the attacks on the Twin Towers was exactly what Al-Qaida wanted. And what have we achieved? Did we eradicate Al-Qaida? Not even close, and in the process we created something worse. There's always something to be said for rational thinking, showing we haven't learnt in 14 years is hardly rational.
