Iran, Russia and Homeland Security Responses to President Trump’s Bombing of Iranian Nuclear Facilities

The responses to President Trump demolishing the Iranian nuclear program last night have not all been positive. 

In Iran, it was reported this morning that the  Iranian Parliament has just ordered the Strait of Hormuz be CLOSED. The Strait handles 20% of global daily oil shipments in the world  — its closure could send prices soaring. The step will come into effect, pending a final decision by Iran’s Supreme Council.

Marco Rubio contacted China to tell Iran not to close the Straight.

U.S. Secretary of State Marco Rubio on Sunday called on China to encourage Iran to not shut down the Strait of Hormuz after Washington carried out strikes on Iranian nuclear sites.

Rubio’s comments on Fox News’ “Sunday Morning Futures with Maria Bartiromo” show came after Iran’s Press TV reported that the Iranian parliament approved a measure to close the Strait of Hormuz, through which around 20% of global oil and gas flows.

Russia was not too happy about the bombing as well.  The Jerusalem Post reports:

In a post on X/Twitter, Medvedev suggested that the United States’ attacks on three sites in Isfahan, Natanz, and Fordow backfired, and led to the opposite result from what US President Donald Trump had set out to achieve.

“We call for an end to aggression and for increased efforts to create conditions for returning the situation to a political and diplomatic track,” the ministry said.

In response, Homeland Security is warning Americans of potential negative or deadly responses in the US.

In response to the bombing, Homeland Security has also issued a statement.

Summary of the Threat to the United States

The ongoing Iran conflict is causing a heightened threat environment in the United States. Low-level cyber attacks against US networks by pro-Iranian hacktivists are likely, and cyber actors affiliated with the Iranian government may conduct attacks against US networks. Iran also has a long-standing commitment to target US Government officials it views as responsible for the death of an Iranian military commander killed in January 2020. The likelihood of violent extremists in the Homeland independently mobilizing to violence in response to the conflict would likely increase if Iranian leadership issued a religious ruling calling for retaliatory violence against targets in the Homeland. Multiple recent Homeland terrorist attacks have been motivated by anti-Semitic or anti-Israel sentiment, and the ongoing Israel-Iran conflict could contribute to US-based individuals plotting additional attacks.

Additional Information

The Iranian Government has publicly condemned direct US involvement in the conflict.

• Both hacktivists and Iranian government-affiliated actors routinely target poorly secured US networks and Internet-connected devices for disruptive cyber attacks.
• US law enforcement has disrupted multiple potentially lethal Iranian-backed plots in the United States since 2020. During this timeframe, the Iranian government has also unsuccessfully targeted critics of its regime who are based in the Homeland for lethal attack.
• If Iranian leadership were to issue a religious ruling calling for retaliatory violence against specific targets in the Homeland, it could increase the likelihood that a supporter of the Iranian regime is inspired to commit an act of violence in the Homeland.
• Since the start of the conflict, we have seen media releases by foreign terrorist organizations (FTOs)—
  including HAMAS, Lebanese Hizballah, the Houthis, and the Popular Front for the Liberation of Palestine, among others—some of which have called for violence against US assets and personnel in the Middle East because of Israel’s attack.
• The conflict could also motivate violent extremists and hate crime perpetrators seeking to attack targets perceived to be Jewish, pro-Israel, or linked to the US government or military in the Homeland.

America is actually safer today.
