The new military conflict that erupted last week between Israel and Iran has been hugely disruptive in a multitude of ways, both regionally and around the globe, including for the United States to a certain degree.

On Monday, House Speaker Mike Johnson (R-LA) revealed that he'd called off an imminent planned visit to Israel to address the Jewish nation's parliament this coming weekend, according to Fox News.

The cancellation coincides with the State Department's issuance of a strong warning against any travel to Israel by Americans amid the ongoing armed conflict with Iran, largely because of the risks posed by intermittent Iranian missile strikes and drone attacks, to say nothing of the elevated threats of terror attacks and potential civil unrest.

Planned visit postponed

In a statement on Monday, Speaker Johnson revealed that, in consultation with his Israeli counterpart, he had postponed his plans to address the Israeli Knesset on Sunday.

"Due to the complex situation currently unfolding in Iran and Israel, Speaker Ohana and I have made the decision to postpone the special session of the Knesset," the speaker said.

Johnson added, "We look forward to rescheduling the address in the near future and send our prayers to the people of Israel and the Middle East."

Johnson stands with Israel against Iran

Fox News reported that Speaker Johnson, a staunch ally of Israel, expressed his support on Friday for Israel's preemptive strikes against Iran's nuclear facilities, weapons programs, and military leadership, which Israel deemed immediately necessary to constrain and eliminate the dire threat Iran's Islamist regime poses to itself, the broader region, and the world at large.

"Israel and the United States have been united, including in our shared insistence that Iran must never obtain a nuclear weapon," Johnson said in a statement at that time. "President Trump and his administration have worked tirelessly to ensure that outcome."

"Unfortunately, Iran has refused to agree and even declared yesterday its intent to build a new enrichment facility," he added. "Israel decided it needed to take action to defend itself. They were clearly within their right to do so."

State Department advises against any travel to Israel

The postponement of Speaker Johnson's planned visit to Israel comes as the State Department has issued its highest-level warning for Americans against travel to Israel as well as the Palestinian-controlled West Bank and Gaza.

A "Level 4 - Do Not Travel" advisory because of the dangerous risks posed by armed conflict, terrorism, and civil unrest in those particular areas.

Specifically for Israel, the State Department warned, "The security situation in Israel, including Tel Aviv and Jerusalem is unpredictable, and U.S. citizens are reminded to remain vigilant and take appropriate steps to increase their security awareness as security incidents, including mortar and rocket fire and armed UAV intrusions and missiles, can take place without warning."

The advisory further noted that additional restrictions were in place for particularly sensitive areas -- including the border regions near Gaza, Egypt, Lebanon, and Syria -- and that "Any official travel of U.S. government personnel within these areas requires approval from the Embassy’s security office. Additional travel restrictions may be imposed on U.S. government employees under Chief of Mission security responsibility, with little to no notice due to increased security issues or threats."

As for when Speaker Johnson might reschedule his planned address to the Israeli Knesset, that likely is wholly dependent upon whether the Israel-Iran conflict escalates and how long the fighting lasts before any potential ceasefire deal or peace agreement takes effect.
