Tariffs can help the US prepare for conflict since they can lower foreign reliance, Ray Dalio says.Dalio wrote on Wednesday that such taxes are "necessary" in times of an international power struggle.The billionaire has regularly said he thinks the world is moving into a time of a high risk of war.Investing mogul Ray Dalio said tariffs aren't just a matter of tax revenue they're also a way for countries to prepare their economies for times of conflict and war.As the Trump administration announced reciprocal tariffs on China, the European Union, and dozens of other regions on Wednesday, Dalio wrote in a LinkedIn post that import taxes were "necessary in times of an international great power conflict."The billionaire's reason? They tend to lower reliance on foreign supply chains.Dalio, who founded the hedge fund Bridgewater Associates, wrote that the tariffs "can reduce both current account and capital account imbalances.""Which, in plain English, means reducing the dependencies on foreign production and foreign capital, which is especially valued in times of global geopolitical conflicts or wars," the billionaire added.He wrote that this makes local companies less efficient because global supply chains are stifled but more survivable as long as domestic consumers can still buy enough of their goods.Dalio's post wasn't specifically dissecting the Trump administration's tariffs, so he's not necessarily saying that the White House introduced these taxes in expectation of war.Rather, he wrote about tariffs in general, highlighting their typical effects and the potential motivations for governments to introduce such measures.For example, the billionaire wrote that tariffs tend to bring inflation to the countries that introduce them and stagflation to the world.But Dalio's point about a potential "international great power conflict" aligns with the billionaire's regular warnings that the world is moving toward a period of great strife and a high risk of war.The billionaire published a book about this belief in 2021, in which he predicted that US-China competition would bring fundamental, messy changes to how the world is run.Either way, US debt must be tackled, Dalio saysIn his post on Wednesday about tariffs, Dalio recalled another of his usual points about the state of the world: He believes the US government's debt crisis must be solved. The federal debt-to-GDP ratio is about 120%."The production, trade, and capital imbalances (most importantly the debts) must come down one way or another, because they are dangerously unsustainable for monetary, economic, and geopolitical reasons," he wrote.Dalio warned in February that debt would cause a "heart attack" for the US financial system if left to accumulate."You're in a high risk of this heart attack, essentially, and now what are you going to do about it?" he said.He said at the time that while Elon Musk's Department of Government Efficiency would seek to slash the government budget, those efforts alone wouldn't be enough to fix the debt crisis.Bridgewater Associates and Principles, Dalio's book brand, did not respond to comment requests for Dalio sent outside regular business hours by Business Insider.Recommended video

Vladyslav Plak and his team run Drone Fight Club, a school that teaches Ukrainians how to fly drones in combat. Vladyslav Plak/Drone Fight Club 2025-04-03T04:57:41Z SaveSaved Read in app This story is available exclusively to Business Insider subscribers. Become an Insider and start reading now.Have an account? Vladyslav Plak's school uses a simulator and practice ranges to teach Ukrainians to fight with drones.Only a third of people who try the course actually succeed in becoming a drone pilot, he says.Playing music and sewing are two skills that often tell Plak that a candidate is the right fit.This as-told-to essay is based on a conversation with Vladyslav Plak, the CEO of Drone Fight Club, a Kyiv-based company that trains combat drone pilots for the Ukrainian military. The following has been edited for length and clarity.Not everyone can learn how to fly a drone to fight the Russians. But over the years of training pilots, I've figured out ways to tell if someone fits the role.Since Russia invaded my country in 2022, we've worked with thousands of Ukrainians at Drone Fight Club. Only a third of the candidates who come to us make it all the way to certification. We don't just train men; about 15% of our students are women.Our country's battle drone industry is still young. But we've already found that most people wanting to be combat drone pilots are not ready for the studying required. Our war environment changes quickly and is difficult to navigate, and we don't have enough time to work with people who are not completely suited for the job.It's like "Top Gun." Be the best, or get out. At the zero line, you don't get a second chance. You are either alive, or you get killed.Musicians make for great pilotsBeing a good combat drone pilot is more complicated than just quick reflexes. It is about being able to make the right decision at the snap of a finger.When we screen candidates, we tell them to watch two balls: one green and one red. Then, we tell them which ball to catch. If their reaction speed is slower than half a second, it is not fast enough. This is the top requirement for all pilots.Fine motor skills are also very important because the drone controls are sensitive. If one of our candidates works with a hammer in their day job, they may be good at big movements, but it may be hard for them to be a drone pilot.However, if they play the piano or a similar instrument, they will usually learn fast. Knowing how to play music is a strong sign you will be a successful drone pilot.To be good with music, your brain has to be wired to think ahead. You have to multitask and plan your next steps while you are already using your fingers for finer movements.When you know how to think ahead, your choices will be made with foresight. Those choices matter when you fly in battle. Basic courses at Drone Fight Club last a minimum of three weeks. Drone Fight Club Women who excel at sewing are also often great combat drone pilots. Here, it's the same. They need to think ahead to envision the bigger picture of what they want their clothing material to look like while simultaneously making decisions and using fine finger movements.Generally, our good combat drone pilots are also people who can focus on the task at hand. If your mind is jumping between everything you see, you will lose your concentration.From the simulator to the rangeAt Drone Fight Club, basic courses last a minimum of three weeks and have an exam each week. If you fail one exam, you are dropped from the class and advised to repeat the course.Lessons at our school are split between our simulator, theory lessons, and indoor and outdoor practice ranges.Our simulator, Drone Fight Simulator, is made to work with two pilots who can team up, and the scenarios are all based on the real missions that our guys fought.The same rules that we fight with on the front lines are put in our simulator. When the soldiers come back, they tell us exactly what happened, and we update the simulator with their battles. Drone Fight Club has developed one of several simulators used by Ukrainians to train their pilots for war. Drone Fight Club Just like with learning to fly a plane, you go through a pre-mission checklist, with things like checking the propellers and the data link. On the battlefield, if you forget one of these things, your mission can be a total failure.After using the simulator, students also go onto our target ranges. Each is in Ukraine and is up to four kilometers (2.5 miles) long.Our space is limited because of the war, but it's important that the range is large. In the war, our enemy can be 20 kilometers away. To effectively send a drone into combat, you have to understand what it means to fly long distances over different terrain, in different weather, and with jammers affecting your drone.When this war ends, we might start to help outside nations and militaries with their drones. We will be glad to help friendly nations defend themselves.It's not a matter of whether the war will end, but when it will end. I believe that this war must stop soon. It is costing too many lives.Recommended video

Players fond of CRPGs will remember the Baldurs Gateseries for its compelling storylines and wonderful cast of characters, and Baldurs Gate 3 brings the same character-focused flavor to modern screens. This time around, players encounter various survivors who escaped a recent skirmish against mind flayer invaders from Faerun. Not only that, but all of them have to eliminate illithid tadpoles inside of them before transforming into mind flayers themselves.
