your seeming fair and open minded 'we can all work out our differences' is another man's blinkered view and tbh, I'm not alone in not knowing the solution.
What's yours then.
- Support neighbouring nations to firstly take back ISIS territorial gains through logistics, training and intelligence sharing.
- Withdraw support for rival factions in Syria to help stabilize the region and allow for more focus to be put on ISIS.
- End foreign policy that arms nations that fund and supply terror organisations.
- End foreign policy that seeks to remove oppressive regimes when no suitable alternative to the regime is available and there isn't the plan or resource to do so effectively.
-End all air/drone strikes against targets in urban areas to prevent civilian deaths that fuel extremist recruitment drives.
-Pursue political means to fight terror organisations once the ISIS military threat is nullified.
- The sense to recognise when a strategy is not working and the ability to adjust our approach when required.
That's just some possible ideas and they would be extremely difficult and likely yield mixed results but would be infinitely preferable to the policies of the past few decades.
