Trump Claims the US Has Achieved Regime Change in Iran, But Experts Say Killing Leaders Isn't Enough

politifact

• President Trump and Defense Secretary Hegseth claim the US has accomplished regime change in Iran after killing Supreme Leader Khamenei and other top officials in an ongoing war that began in February.
• Foreign policy experts argue that true regime change requires dismantling governing institutions and ideology, not just replacing leaders, and Iran's theocratic structure remains intact.
• Iran's new leadership, including Khamenei's son who took power, appears to be more hardline than before, while key institutions like the Revolutionary Guard Corps maintain control.

Trump's 2025 tariffs destroyed the old trade system, but regional trade blocs are building a new one without America or China

voxeu

• Trump's April 2025 global tariffs and China's export controls triggered "World War Trade," destroying the US-led global trading system that had anchored commerce since WWII.
• Rather than collapse into protectionism, countries representing 75% of world trade chose restraint and began rapidly signing regional trade agreements to diversify away from US-China dependence.
• A new "solar system" of interconnected trade blocs is emerging through "domino regionalism," with the EU and trans-Pacific partnerships serving as major hubs that maintain rules-based trade without requiring a single hegemon.

America is on track for negative immigration for the first time in 50 years, threatening economic growth and Social Security

brookings

• The U.S. is projected to experience net negative migration in 2025 for the first time in half a century due to Trump administration policies that have drastically reduced immigration inflows while increasing deportations.
• This immigration decline threatens to reduce GDP growth by up to 0.26 percentage points and cut consumer spending by $40-60 billion in 2025, while worsening Social Security's long-term financial health by potentially 25%.
• Immigrants have generated a $14.5 trillion fiscal surplus from 1994-2023, paying more in taxes than they received in benefits, making reduced immigration economically harmful rather than beneficial for American workers.

Trump Faces Three Bad Options as US-Israel War with Iran Drags On

atlantic_council

• A fictional US-Israeli military campaign against Iran has destroyed much of Iran's military capability but created new problems, including closure of the Strait of Hormuz and soaring energy prices
• Trump can seek a quick exit through concessions, adopt a grinding war of attrition, or escalate dramatically with ground troops—but each path carries major risks
• US and Israeli interests are diverging as the conflict continues, with Israel more willing to accept global economic chaos to eliminate the Iranian threat
