Iran's vulnerability

Somebody (probably Iran indirectly, if not directly) has exposed Saudi Arabia's vulnerability to attacks on its oil infrastructure. I'm a little surprised at that, since almost all of Iran's oil exports are shipped through their Kharg Island terminal, and an attack or unfortunate "accident" on that facility (not of course by anyone who would admit to it) would essentially shut down their remaining oil exports. They are even more vulnerable that Saudi Arabia to attacks on their oil exports.

It will be interesting to see if such an "accident" or "incident" occurs sometime soon.
