In an address to a plenary session of the Knesset today, Israeli Prime Minister Benjamin Netanyahu emphasized Israel’s military prowess and its strong relationship with the United States in explaining why Iran would do well to refrain from attacking the Jewish state.

He pointed to the unprecedented relationship between himself and President Donald Trump, having returned from a record-breaking seventh visit to the U.S. president, a number unmatched by any other world leader. He also praised the cooperation between the two countries’ security forces, which he also said was unprecedented.

“I recently returned from my seventh meeting with the president of the United States since he was elected,” he told the session. “Our security agencies and their security services — there has never been anything like this.”

The prime minister also praised Israel’s strength and readiness, saying that in partnership with the U.S., Israel has degraded the threats it had faced, in an apparent reference to the war with Gaza and Iran’s proxy terror groups.

“Israel has never been stronger,” he declared. “No one knows what the day will bring. We are prepared for any scenario.”

Netanyahu also said that he had sent a message to Iran warning of terrible consequences if it attacked Israel.

It would be “perhaps the worst mistake in its history,” he said. “We will respond with a force that they cannot even imagine.”

“This is not the time for argument,” he continued. “In these days, on the eve of Purim, in those days as in this time, we need to close the ranks of the people, stand shoulder to shoulder.”

“I trust in our strength. I trust our commanders. I trust our fighters. I trust our people. I trust you, the citizens of Israel,” he concluded. “We have already proven that when we stand together, we achieve great achievements. On the eve of Purim, we will stand together, and with God’s help, we will ensure the eternity of Israel.”
