I first saw speculation about Israel possibly conducting a false flag operation and blaming Iran in order to get the US to retaliate, and thought nothing of it. However, I ran across an interview a former CIA official who was saying the same thing and decided the story might have legs. Here is the radio interview with Philip Giraldi.
Apparently a retired ex CIA officer is not the only one thinking this.
The top American military officer has warned Israel against orchestrating ‘USS Liberty Part II’ to provoke a US-led war against Iran.
The fact that American officials have to issue these types of warnings to an “ally” is frightening, and speaks volumes of the relationship between the two countries.

What a croc this is! Back up your bs or stop spewing it! Who’s the CIA officer? What’s your source for the “speculation” of a false flag operation? What military officer has warned Israel?
Is there ever anything remotely true to this story? Highly unlikely.
