Just days before Mr. Trump’s presidential campaign said it was targeted by Iranian hackers, a top federal cyber official delivered this ominous prediction: Cyber chaos will come to be seen as routine trouble, akin to bad weather on Election Day.

That was a key message from Jen Easterly, director of the Cybersecurity and Infrastructure Security Agency, who spoke at the Black Hat hacker convention in Las Vegas last week and warned that cyberattacks will only grow more common. Washington Times reporter Ryan Lovelace was at Black Hat and has more details on how CISA seems to be preemptively downplaying inevitable cyberattacks on U.S. presidential campaigns, election infrastructure and other pieces of the country’s democratic system.

Ms. Easterly’s warning came shortly before Microsoft revealed last Friday that it has information about new Iranian efforts to influence the U.S. presidential campaign, including one case in which Iranian hackers allegedly targeted a presidential campaign with an email phishing attack.

On Saturday, we seemingly learned more about such attacks. Mr. Trump’s presidential campaign said that it had been hacked and suggested Iranian actors were involved in stealing and distributing sensitive internal documents. The campaign provided no specific evidence of Iran’s involvement, but Politico reported over the weekend that it received internal Trump campaign documents from a mysterious individual named “Robert.”

When you put all the pieces of the puzzle together, one thing seems clear: A concerted effort by U.S. adversaries to undermine democracy and disrupt the presidential election is now underway.

And speaking of Iran, the U.S. and Israel are bracing for a possible attack by Iran or its proxy groups against Israel. Iran has vowed to retaliate after a strike in Tehran late last month killed Hamas political leader Ismail Haniyeh. Israel has not claimed responsibility for the incident but is widely believed to be behind it.

U.S. Defense Secretary Lloyd Austin on Sunday ordered a guided missile submarine to the Middle East and is telling the USS Abraham Lincoln aircraft carrier strike group to sail more quickly to the area. The Pentagon in recent days has dispatched other military assets to the region, presumably to prepare to aid Israel in repelling an Iranian attack. Mr. Austin told Israeli Defense Minister Yoav Gallant in a Sunday phone call that America will “take every possible step to defend Israel.”

There are mounting fears that Iran will call on its most powerful regional ally, Lebanese Hezbollah, to unleash the full might of its forces on Israel. Former U.S. military officials say they believe such a step is imminent.

“I think we are hours, maybe days, not weeks, away from Lebanese Hezbollah entering this fight, and that’s always been the big variable,” retired Gen. Kenneth F. McKenzie, former head of U.S. Central Command, told CBS’ “Face the Nation” program on Sunday.

Amid the possibility of a wider war, a last-ditch push for peace in the Gaza Strip is taking shape. The leaders of France, Germany and Britain on Monday endorsed calls for a cease-fire in Gaza, the return of scores of hostages held by Hamas and the “unfettered” delivery of humanitarian aid.

In a joint statement released Monday, they backed the latest push by the U.S., Qatar and Egypt to broker an agreement to end the 10-month-old war between Israel and Hamas.

One of the world’s fastest fighter jets, the F-16, took its time getting to Ukraine. Now, the question is how much of a difference the U.S.-made plane can make in an encumbered ground battle of attrition with Russia after 2½ years. Military correspondent Mike Glenn has a deep dive on the potential impact of the American fighter jets, which will augment and eventually replace Ukraine’s fleet of aging Soviet-era fighters.

The arrival of F-16s comes at a pivotal moment in the fight, as the Ukrainians are now taking the fight to the Russian army on Russian soil. An official in the Kursk border region of Russia on Monday urged more residents to evacuate the area, where Russian forces are still scrambling to respond to a surprise Ukrainian attack after almost a week of fierce fighting.

Russia’s emergency authorities say more than 76,000 people have fled their homes in areas of Kursk, where Ukrainian troops and armor poured across the border on Aug. 6, reportedly driving as deep as 19 miles into Russia, dealing both a military and psychological blow to Moscow’s forces.

The two sides are also trading blame for an apparent fire at Ukraine’s Zaporizhzhia Nuclear Power Plant. In a post on X, Ukrainian President Volodymyr Zelenskyy blamed “Russian occupiers” for the fire, and he urged the United Nations to hold Russia accountable.

The Kremlin blamed the fire on Ukraine and accused Ukrainian forces of perpetrating “terrorist activities.”

The looming November election could determine the fate of Jews in the United States and Israel — together, 82% of the world’s Jewish population. That’s the argument from Washington Times columnist Don Feder, who writes that “once again, Jews confront an implacable foe dedicated to their destruction.”

“The genocidal maniacs are supported by a diverse band of useful idiots, mostly in the Democratic Party,” he writes.
