Nah, they're not all that different. If anything, the ones with shaped charge warheads are worse. It's a case of someone ringing the bell and Pavlov's dogs salivating, that's all.

Somebody wants to damage these oil tankers without sinking them or creating a major oil spill. They’re using a charge above the waterline? Something else is afoot. I notice that both tanker crews were ‘rescued’ by the Iranians. Could this be an elaborate hostage-taking exercise?
