U.S. intervene in a domestic issue in Iran?
Not just "no," but HELL NO.
I throw that in as a thought because 1) wouldn't be the first time we've intervened in various ways to get hostile governments replaced 2) Iran is definitely a hostile government, openly trying to get nuclear weapons with the threat to use them against us and/or Israel, our ally, so it's within our interest to support regime change overtly or covertly.
Not saying we should or shouldn't, I would want to know the exact plan before commenting, as well as who's running said plan, and even with a solid strategy, poking our noses in other country's affairs is always debatable, especially in the Middle East. It's just one of the things that went through my mind seeing the story pop up.
