Arming tankers is not a good idea.
That might only provoke Iran into sending gunships ahead of the assault teams to suppress defensive fire, or respond to defensive fire by sinking the tanker by multiple means.

Why do banks have armed guards and saves? Maybe banks should just put their money in a pile in the parking lot and guard it with an old lady holding a broom. After all, having arm guards just invites people to bring guns to rob them. What an escalation of violence.
