Few people are going to want to owe the USA favours for occupying their country.
Its easy to advocate violence as a panacea when it clearly isn't, and is in fact a major cause of the Paris attacks.
How do you defeat a land power with a civilian population without boots on the ground? If you do have boots on the ground, how do you avoid a quagmire cluster**** mess akin to Afghanistan or Iraq? How do you pay for another extravagant foreign venture? Bearing in mind ISIS was
born in the chaos of the post-invasion Iraq and later migrated to Syria. Who are you going to bomb? How are you going to differentiate? How are you then going to claim those areas from ISIS and for whoever it is you think you're fighting for?
Air-power based interventions based on bombing strategic targets only work if you're fighting in support of someone who can actually capture territory and occupy it. As the major forces currently involving in air intervention (Russia, Britain, France, USA) currently back different factions and have no actual plan for a post-ISIS settlement this is a meaningless action - but every civilian who dies in those bombing raids will have a relative who might have been content to live under ISIS dominion but will now instead want to pick up a Kalashnikov and fight back.
People in ISIS-occupied territories are content with ISIS rule as they have healthcare and a form of order there. What alternative can the USA offer but collateral damage bombing and the deaths of more family members? Every aggressive action taken in Syria which harms civilians makes them more likely to buy the ISIS narrative.
I think ISIS has to be militarily defeated. I don't think the USA, Britain or France should be the leading force in achieving that. A NATO-backed Turkish/Israeli/Saudi force would be more appropriate, if you could get any of them to move beyond rhetoric and stop using the war as an excuse to further their own agendas. I think the Europe, Russia and the USA has to come to some kind of agreement on what exactly post-ISIS Syria will look like and decisively back a big-tent strategy to achieve that, militarily. It won't be the end - ISIS fighters and Islamists will remain a problem indefinitely - but without territory ISIS loses its claim to being a caliphate and therefore its sovereignty and apocalyptic-cult pull over Islamists worldwide.
ISIS as a state is an aberration and a geopolitical irrelevance; a quixotic band of monomaniacal idiots who preside over a pile of ashes and call it a caliphate. They
want a Western over-reaction to sell their narrative, sow division and keep the flow of foreign fighters and donation money coming in to buoy a tragicomic failed state. They
want a huge confrontation with Christianity - the name of their magazine - Dabiq - is the site where the supposed last battle between the 'Romans' and Islam is going to be fought, and they're obsessed with bringing this into realization. Let a moderate Muslim power defeat them which can offer some kind of alternative than the bombed-out ruins Hollande is offering.
Can we also remember that the currency we're frivolously spending on a gaming forum is ****ing human lives? Even 'Islamists' are people and many ISIS foot soldiers aren't even Islamists.s
