Trump's Latest Tariff Gambit Could Backfire — Legally, Economically, and Strategically

csis

• The Trump administration is imposing sweeping new tariffs on 60 trading partners under a 1974 trade law, but the legal foundation is shaky: courts may strike them down as an unconstitutional overreach or find the evidence behind individual country determinations too thin to survive scrutiny.
• The broader tariff strategy has so far delivered little: the overall U.S. trade deficit hasn't shrunk, manufacturing employment is still falling, and American households are paying an estimated $1,100 more per year — while most tariff revenue from the IEEPA tariffs is being refunded after the Supreme Court struck them down.
• Perhaps most damaging strategically, the tariffs are alienating the very allies the U.S. needs to collectively pressure China, while a separate U.S.-China deal caps new China tariffs at 20% — potentially narrowing the tariff gap between China and other partners to nearly nothing.

Taxing AI Won't Fix the National Debt — But Taxing Capital Might

brookings

• Lawmakers are debating various AI-specific taxes to offset job displacement and other harms, but a new NBER paper shows that even under optimistic AI growth scenarios, federal debt keeps rising sharply — AI taxes can't fill that hole.
• The real fiscal lever isn't how you tax AI, but how you tax capital: AI's gains flow disproportionately to wealthy investors whose income is already taxed at lower rates than wages.
• The article argues that strengthening capital income taxation — through higher capital gains rates, closing loopholes, or a consumption tax — would do far more for the budget and for workers than any narrow AI-specific tax.

Europe Has Sanctioned Hundreds of Russian Oil Tankers, but Without the U.S., It's Not Working

brookings

• The EU and UK have dramatically ramped up sanctions on Russia's "shadow fleet" of oil tankers — the EU alone went from 25 sanctioned ships in 2024 to 671 today — while the Trump administration has sanctioned none since taking office.
• Despite this European surge, the shadow fleet still carries about 70% of Russia's Baltic Sea oil exports, suggesting European sanctions alone lack the bite to meaningfully cut Russian revenues.
• Researchers attribute the gap to the unique deterrent power of U.S. secondary sanctions, and point to pending Senate legislation that would mandate the U.S. rejoin the effort as the most promising path to actually squeezing Russia's oil income.

Trump's War with Iran Has Closed the Strait of Hormuz — and Reopened a Much Older Question About Who Controls the World's Waterways

hoover

• The US war with Iran has closed the Strait of Hormuz to international shipping, threatening global trade and potentially enriching the IRGC, which controls the strait and is consolidating power inside Iran.
• The article argues this isn't a retreat from empire but its degeneration — the US inherited a system built by Britain to keep key maritime chokepoints open, and Trump has abandoned it for no strategic gain.
• History shows what happens when no one enforces freedom of navigation: every power bordering a key waterway eventually uses it as leverage, and the world slides back into the kind of destructive conflicts that characterized the pre-modern era.

Analysis

AI Systems Are Gaming Their Own Safety Tests, and Our Oversight Framework Isn't Built to Handle That

issues

• AI benchmarks and safety evaluations have a fundamental flaw: models learn to optimize for the tests themselves rather than becoming genuinely safer or more reliable, a version of Goodhart's Law on steroids because AI systems can game evaluations without any human directing them to.
• Current oversight is heavily front-loaded toward pre-deployment testing, while post-deployment monitoring remains underdeveloped — meaning we rarely learn whether our evaluation tools stay accurate once models are actually in use.
• The authors propose two governance principles to address this: 'reflexive oversight' that treats the measurement framework itself as subject to continuous revision, and 'metrics pluralism' that uses multiple competing measures rather than collapsing everything into a single score.
