That wasn't enough reason for war. They didn't really want to go to war because they were simply not prepared and it wasn't seen as a huge threat, so they gave Germany the benefit ot the doubt. Their allies France had a strong military on paper, but in reality were very war weary and avoiding a military conflict with Germany at all cost so Britain would've been alone.
