I agree that clear, focused speeches are no longer to be found. It is a shame actually as what people want to hear in times of crisis is not who is to blame, this is just a first impulse it is rather that we are strong enough that we can cope with the situation and that we know what we are fighting for.
The comparison between the two speeches is really interesting and it seems that the claim made in
this post is right it is enough to say we are strong, we are important no one should dare attack us and live, a more realistic perspective is needed as to the need to know that the fight might be long and we know what we are fighting for.
