Sir Julian Lewis: I am concerned about one problem that may arise. We have now got to a stage where the Government have given permission for the Americans to strike back against, for example, missile batteries launching at targets that might include our own bases. I am not clear what would happen – and I hope it never has to come to this – if our bases were successfully attacked and damaged. Are the Government still saying that only the Americans should retaliate against those batteries, or should the RAF have a role as well? I am not anxious to escalate, but I do not see where the logic lies in America being able to retaliate, when our own armed forces cannot, following an attack that has successfully damaged one of our own bases.
