This answer to the question Why DAESH does not attack or even threaten to attack Israel? implies that the US and UK are supportive of DAESH, indirectly providing finances to them through Saudi Arabia. I'll pass on the details, but enough to say that there is little sources to support that answer.
So it sounds a lot like conspiration theories to me. I did flag it for low-quality and downvoted. However the flag was declined with
flags should not be used to indicate technical inaccuracies, or an altogether wrong answer.
I haven't been much active in flagging/moderating here until recently, but is it ok to leave such answers lying around?
