Just when I thought I don't believe in conspiracy theories...

It's possible that Iran planned to murder the Saudi ambassador in DC, which would be an act of war

But the Iranian government is not completely mad, and I would think it was unlikely

Particularly unlikely is the use of Mexican drug cartels to carry out a bombing

It's like a B movie

This really looks like a clumsy US/Israeli conspiracy
