What’s Really Going on with Iran? (Rush Limbaugh via Freep)

RUSH: So I got an interesting email. “Mr. Limbaugh, what do you think or who do you think is really stirring up this business with Iran?” It’s a good question, ‘cause you know who’s buddy-buddy with Iran and who has been over there attempting to undermine Trump administration on policy with Iran is none other than John Kerry — the haughty John Kerry, who served in Vietnam.
I think that his daughter married some Revolutionary Guard assassin or something, some such thing. His daughter married somebody from over there. The foreign minister’s third cousin, I don’t know what, but there’s some family tie now. And of course, the Iran deal in the Obama administration was one of their great things, they believe, and Trump has come in and has summarily ripped it apart and backed out of it, which has cost the Iranians 150 (what was it?) billion dollars or million dollars, whatever we dropped on the tarmac there.

So they’re ticked as they can be over sanctions and Trump’s relegating them to this secondary status, and the fact that John Kerry (you can put Obama in this sentence or not) has been actively advising the Iranians on how to deal with Trump…
