Obama and Iran

Obama has apparently sent both conciliatory and antagonistic signs to Tehran since he assumed power.
Some have complained that Tehran has not responded positively enough. But, as Flynt Leverett and Hillary Mann Leverett note, this is because Obama has done nothing to cancel Bush's hundreds of millions dollars covert operations program against Iran:
"the Obama administration has done nothing to cancel or repudiate an ostensibly covert but well-publicized program, begun in President George W. Bush’s second term, to spend hundreds of millions of dollars to destabilize the Islamic Republic. Under these circumstances, the Iranian government — regardless of who wins the presidential elections on June 12 — will continue to suspect that American intentions toward the Islamic Republic remain, ultimately, hostile."
