Gents,
Please let's try and be civil. The US Government have taken their decision based on the information THEY have available to them, not what we think they know.
By the same token, perhaps here in the UK we should reconsider whether to accept flights originating from the US carriers until our Government have assured themselves that the poor level of security which existed in the US has been upgraded ?? If that would cause them to squeal, (which I doubt since they more than us will understand the current situation and the measures which need to result) then as Wino says, **** them.
Regardless of all that, our friends and colleagues in the US should have our full support and sympathy in this harrowing time.
