As I'm sure anyone who has been following the news since 1979 is aware Iran and Saudi Arabia aren't very fond of each other. Both view each other as regional rivals and have taken various steps over the years to try to gain dominance. With events in Syria and Yemen, this proxy conflict has heated up, with regards to the latter, it could well lead to attacks on Saudi soil through various proxy groups.
How far do you think this conflict will go? Will we eventually see outright conflict between Iran and Saudi Arabia?
