The Israel-Iran missile and drone war churned violently into its fifth day Tuesday, and uncertainty swirled over whether or not Mr. Trump will order U.S. military forces to assist Israel in striking the most fortified center of Iran’s nuclear program — the mountain-encased enrichment facility at Fordo.

Israel has made the destruction of Iran’s nuclear program the central goal of the war and has already launched several missile strikes on other Iranian nuclear facilities, including Natanz and Isfahan. There is, however, skepticism that Israel has the ability to destroy Fordo without U.S. assistance, because it would likely require a “bunker buster” bomb to decimate the site, which features operations centers buried some 260 feet underground.

Only U.S. bombers are seen as capable of carrying such 30,000-pound precision-guided bombs. At the same time, any targeting of Fordo would be complicated because the facility sits beneath a mountain near the holy city of Qom and is protected by an extensive, Russian-built missile defense system.

The Paris Air Show taking place this week is widely considered the largest and oldest aerospace and defense industry market event in the world, and it opened with a standoff between French and Israeli officials on Monday.

A large black barrier surrounded Israeli defense industry booths at the show on Monday morning following an order from the French government. Israeli officials said Paris Air Show organizers had ordered Israeli defense companies to leave certain weapons systems out of the display.

Israeli defense officials implied France gave the order for commercial reasons, considering the two nations are competitors in the defense industry. The black barriers surrounded the booths of Israeli Aerospace Industries and Elbit Systems, so that only glimpses of equipment could be seen.

While global media attention focuses on the Israel-Iran war, Russian military forces have increased their missile and drone attacks on Kyiv, with an overnight blitz between Monday and Tuesday demolishing a nine-story apartment building in the Ukrainian capital and killing at least 15 people.

Ukrainian officials said more than 150 people were injured by the Russian assault, which featured over 440 drones and 32 missiles that sent explosions echoing across Kyiv for nearly nine hours. The attack signaled an intensified Russian focus on hitting the Ukrainian capital following the recent failure of two rounds of direct peace talks.

Russia launched a similar large-scale drone and missile attack on Kyiv during the first week of June. Some analysts say Moscow seeks to target Ukrainian citizens and destroy Kyiv as retaliation for the massive June 1 Ukrainian drone strike — dubbed “Operation Spiderweb” — that wreaked havoc on several military bases inside Russia.

Israel’s “stunningly successful” strike against Iran’s nuclear and missile programs may be the best example yet of the “burden sharing” approach to foreign policy favored by Mr. Trump, according to Alexander B. Gray, who served in a top national security advisory role during the first Trump administration.

“A militarily and economically advanced regional power whose interests often align with the United States, Israel acted against an imminent Iranian nuclear threat with skill and apparently limited reliance on direct American support,” Mr. Gray writes.

“Washington would be wise,” he writes, “to pocket Israel’s win for the collective West, avoid America’s time-honored tradition of Middle Eastern overreach and redirect strategic bandwidth to the Indo-Pacific.”

Beneath our oceans lies a “wealth of untapped potential: minerals essential for national security, technology and energy independence,” writes Jorge Martinez, who asserts that “China knows this” and has responded by engaging in its own “relentless push to dominate critical mineral resources.”

“That’s why the U.S. must assert its leadership in seabed mining or acquiesce to China’s dangerous chokehold on global supply chains,” writes Mr. Martinez, director of special projects for the America First Policy Institute. “The stakes couldn’t be higher.”

“Roughly 90% of the world’s rare earth minerals are processed in China, giving the Chinese Communist Party enormous leverage over industries vital to America’s future, including semiconductors and defense systems,” he writes. “As demand skyrockets for data centers, advanced computing capabilities and the next generation of warfighting machinery, the CCP’s dominance over these minerals becomes an increasingly potent geopolitical weapon.”
