In Washington, President Obama has secured enough votes in the Senate to survive any major congressional challenge to the Iran nuclear deal, as Sen. Barbara Mikulski (D-Md.) on Wednesday became the 34th Democrat to announce her support for the accord.

In Iran, however, the United States remains Satan number one — at least for the hardliners.

Consider this: Those reports you heard about the "Death to America 2015" graffiti being erased from the walls of the former U.S. Embassy in Tehran? Well, the graffiti apparently has appeared again on the embassy's walls, according to a report by Radio Free Europe/Radio Liberty. The report quotes Iran's, viewed as close to Tehran's mayor, Mohammad Bagher Qailbaf, as saying that the slogan is back, only now it does not mention any specific year.

Here's the link to the Farsi-language story with images of the fresh graffiti.

And for those moderate Iranians who feel like celebrating the nuclear deal and a new rapprochement with the West, don't wear any clothing emblazoned with the American or British flags. Police in Tehran are reportedly arresting shopkeepers for selling such attire, according to Iranian media.

Police chief Gen. Hossein Sajedinia was quoted by the semi-official Islamic Students News Agency as describing the flags as "Satanic symbols," and the garments imprinted with them have been seized.

Any stores, he added, would be shut down if they dare to sell such clothing.

Such actions highlight the extent to which the internal struggle between Iran's moderates and hardliners over the nuclear accord has spilled into the streets of Tehran. They come as hardliners are increasingly — and publicly — sounding their displeasure at the new interactions with the United States.

On Tuesday, the head of Iran's Revolutionary Guard, Maj. Gen. Mohammad Ali Jafari, described the United States as the "same Great Satan," despite the nuclear deal. He also reportedly vowed to expand the reach of Iran's missiles and criticized Iranians who wanted improved relationships with the United States, according to a report in the New York Times.

That list includes Iran's President Hassan Rouhani.

“We should not be cheated by the new slogans of this country,” Jafari said, referring to the United States, during a speech at the Tehran Sarallah military base, according to the Times translation of Iran's semi-official Fars News Agency.

The speech followed public comments by Ayatollah Mohammad Yazdi, the head of a powerful clerical assembly, who also declared that the nuclear deal would not alter Iran's foreign policy toward Washington.

"The Islamic Republic of Iran considers the U.S. its number one enemy," Yazdi said, according to the Islamic Republic News Agency and translated in a Fox News report. "If you try to discover the root of the sedition that is happening around us today, you will identify U.S. as its main supporter."
