Are UK bombs making a difference in Syria? The ones that take out Stone Age terrorist are and will. Tasking and targeting are the keys. Parliament voting "yes" doesn't mean the RAF have to suddenly do anything.
When there are valid, confirmed targets there, they will hit them. If they hit anything else, the BBC would be all over that too. And there will be another IHAT.
Ops will be conducted cautiously and carefully against confirmed targets.
