In a statement, Hamas praised Tehran-its key strategic ally-for standing by the Palestinian cause and backing the resistance against Israel over decades, including during the current war that began in October 2023.

Iran is often portrayed as one of the world’s most dangerous actors, but with its attacks on Iranian defenses, nuclear sites and proxy militias, Israel has exposed a compromised and weakened adversary.

"Our support for Gaza and our defense of our country against the Zionist aggression against it has continued," a Houthi source told Newsweek.

For much of the 20th century, the US and Iran maintained friendly relations. During the Cold War, Washington depended on the Shah of Iran to counter Soviet influence in the oil-rich Middle East.

D-Day has arrived for Israel and Iran. After years of covert warfare, cyberattacks, and clandestine operations, Israel has taken the initiative. In the early hours of Friday, June 13, it launched a direct assault on the heart of Iran’s nuclear program.

What was the context for these attacks? What kind of damage has been inflicted? How has Iran responded? How has the world responded, and what happens next?

The United States is the main international backer of Israel, Iran's biggest regional foe. It is also a close ally of Sunni Gulf monarchies which for years pursued their own rivalry with the Islamic Republic, seeing it as their main regional threat.

Advanced espionage techniques made the most of Iranian vulnerabilities, but Israel’s ultimate aims may still be out of reach.

Iran must understand that there will be grave consequences for any actions they take in response to this justified attack.
