As US President Donald Trump threatens renewed attacks against Iran, Tehran’s intermittent strikes on commercial vessels have left the two sides locked in a painful economic standoff.

Explosives attached to the outside of a tanker by fighters in a speedboat damaged the larger vessel’s engine in the Strait of Hormuz, the first attack of its sort in the current conflict and a tactic Iran has used before against commercial shipping.

After four years of relative calm, the war pitting Yemen’s Houthi militia against the country’s internationally recognized government and its backer Saudi Arabia is raging again.

Ukraine’s defense against Russian attacks depends heavily on US satellites, not only for warning of incoming missiles but also for the communications that keep drones and frontline forces operating.

In the face of Russian missile and drone attacks, Ukraine needs more than weapons to protect itself. Satellites provide a crucial early warning that a projectile has been launched, as well as information on how to intercept it.

The Houthi attacks on Saudi Arabia are demonstrating the limits of the kingdom’s military prowess — despite defense spending that far outstrips that of its regional neighbors.

Orbital data centers chasing unlimited solar power and boundless real estate increase the risk of potentially catastrophic conflict in space — just as militaries worldwide embrace artificial intelligence and see computing facilities as critical infrastructure.

“There is no easy way out” of the Iran conflict at this point, former US Defense Secretary Lloyd Austin said at a security forum in Poland.

Europeans should increase support to Ukraine in response to Russian hybrid attacks, the head of NATO’s military operations told Bloomberg Television in Poland on Sunday.

Russia had more than 50,000 casualties in Ukraine last month, with as many as 28,000 personnel killed — vastly more than losses by Ukrainian forces, according to a senior NATO military official.

Iran has managed to preserve its missile and drone factories despite months of US and Israeli bombing, officials familiar with the matter said, allowing it to replenish its arsenals while President Donald Trump holds off on strikes ahead of the midterm elections.

President Donald Trump’s decision to move US B-1B bombers from a UK airbase citing terror threats may embolden Iran and Russia’s use of proxies to carry out sabotage attacks, according to current and former British officials.

UK opposition leader Kemi Badenoch played down initial claims her plans for a £10 billion ($13.2 billion) air defense program would amount to a British “iron dome” after the proposal came under scrutiny.

Ryanair Holdings Plc will keep cutting flight frequencies to avoid exposure to unhedged fuel prices during the slow winter months, or shift capacity to markets with lower fees such as Italy and Scandinavia.

The cost of naval operations since the buildup began in January has topped $7.1 billion — not including all the US assets being used to escort tankers through the Strait of Hormuz.

The US tactic of striking Iranian tankers in reprisal for attacks on American warships faces a key obstacle: Tehran likely values putting a hole in an American destroyer more than losing an empty cargo ship.

The Chinese military has developed hypersonic glide vehicles that can launch air-to-air weapons, an advancement meant to threaten high-value targets such as command-and-control aircraft thousands of miles away.

The US’s 2019 exit of a key treaty opened the door for new long-range weapons.

The world is on the cusp of a third missile age, with conventional ballistic weapons proliferating at unprecedented speed in the wake of widespread, battlefield-warping deployment in Iran and Ukraine.

GPS spoofing and other countermeasures meant to knock drones from the skies over battlefields are giving rise to novel navigation systems that will work even in the face of intense jamming.
