Arguably yes, Al Qaeda have been significantly quieter in the last few years, but then I doubt that's just down to getting rid of Bin Laden.
True, and up to a point that's my preferred viewpoint as well. However the world is a much smaller place now, and of course money talks (as does angry Russians with much bigger bombs than us, hence the reason we're not quite ready to poke that bear yet) but morally I don't think we should sit by and let people with the ideology that IS has make any steps forward. If it were simply a case of an internal dispute, let's use Syria as an example, where you have a domestic rebellion then I'm all for sitting back and seeing what happens. Trouble is that led to a power vacuum that IS utilised, and IS have no intention of leaving the evil West alone like Syria under any government would. We had to act.
My problem isn't with the West interfering with other countries, it's more that we're too choosy in where we interfere. There's some proper evil b*stards in Africa that we seem happy to leave alone, and I don't see how that can be right.
