Firstly, my condolences for the events of the past couple of months. Your nation has been exceedingly fortunate to almost entirely keep clear of attrocities like these for years while for the rest of us they are regrettably an all too common occurrance. As a result of this, most of the rest of the world took steps to improve security at source (i.e. on the ground) while America chose to allow people to wander all through their airports. Now that the worst has happened we are all expected to follow whatever the US decides is an appropriate way of acting, are we? It's funny how I have no recollection of any change in US security taking place after any UK or European terrorist attacks.
With full respect but also remembering that the world extends beyond American shores.
