Safe Haven and Provide Comfort (Gag!) rolled together really.
My point is that the Brits entered into an op with an American military support umbrella but then had the rug tugged from under the feet when a rapid withdrawal (on the ground) occurred nearly leaving us left behind as that promised umbrella was, without sufficient notice, taken away. It's a matter of trust ...and long memories!
Edited to say that I feel that this time - regardless of other reasons - it may be wise for the Brits to get out first, because with inadequate AT assets available, history may just repeat itself. And this time it WOULD be a blood bath.
