If you have an acquaintance who is telling you that someone is trying to harm you, and they have good proof that someone is really trying to harm you, it isn't bloody "appeasement" to listen to their warnings and take appropriate protective action.
It isn't appeasement. It is being smart.
Praise YHVH (God) !!!
Thank you UK for waking up, on this obvious national security issue.
