Be like Dolly-kind, accepting of all, and generous to the less fortunate. Sounds easy, but the world says it’s not. Prove em wrong.

@nxthompson Agreed. Climate, food production/distribution, housing…more focus on the bottom of Maslow hierarchy of needs.

Cape Verde showed us it’s cool to care deeply, try hard, dream big, and that even when you come up short there is value in having given it your all. It’s not just about the result but who you become and inspire along the way.

I love this team. I love this run. I love sports.

Putting aside the spin, here's what happened:

The US launched a war of choice against Iran. The purpose was to duplicate the recent success in Venezuela--decapitate the regime, empower new leaders who were willing to cut a deal, leave Iran weaker and more compliant.

Very quickly, it was clear that wasn't going to happen. Iran's leadership had planned for war, the mosaic defense allowed for rapid and resilient response, the regime quickly rallied around a hard core of IRGC/security leadership. A quick victory faded.

Instead, the war became attritional, which played to Iran's strengths. Iran closed the strait, attacked regional infrastructure, imposed costs and waited for the US to de-escalate and accept a negotiated settlement favorable to Iran. That was always the plan.

The US resisted. The goal shifted: military and economic pressure became a lever to force Iran into making concessions on its nuclear program. The administration considered high-risk operations, like seizing Kharg Island or raiding Isfahan to take Iran's HEU stockpile. In the end, the risks were never manageable. The US offered a ceasefire. Iran accepted.

There followed two months of negotiating and posturing. Both sides thought they had leverage. Both tried pressure via "dueling blockades." But Iran always had the advantage: it had already resisted the core US demands while under bombardment, the idea that it would yield under pressure and threats was never especially credible.

Iran had a simple task: resist and extract concessions for reopening the strait. The US lift was heavier: it was demanding major concessions, but lacked the tangible success in war to attain them. The US negotiating position had weakened relative to where it was before the war. Iran's had strengthened.

The deal both sides are moving toward reflects that dynamic. It is not a US surrender--the US is still the stronger power and it can absorb this war with relative ease, thanks to its vast resources--but it is far less than what the US had hoped to achieve.

Iran is not really walking away a winner--its losses since June 2025 are immense, albeit recoverable in time--but it has succeeded in resisting capitulation, and imposed enough costs to extract concessions in return.

This is the hell of plastic pollution.

The photo shows Rio Motagua in Guatemala. It’s a horrible scene. There are many similar places across the globe.

But the good news is that at the end of this year the beaches of Guatemala will come back to old splendor - white sands, blue oceans, green vegetation.

This is thanks to The Ocean Cleanup. Their fantastic river interceptors today pick up 2 - 5 % of all plastics moving into our Ocean.

Nearly all plastics coming into the Ocean originate in 1000 rivers. Ocean Cleanup is ready to vastly expand its operations. Nearly all of these rivers are in middle income countries. The rich have effective garbage collection. The poorest cannot afford much plastic.

I had a wonderful conversation with Boyan Slat the founding father of Ocean Cleanup today. “This is the cheapest global problem to solve”, he said. He needs more investors - companies, philanthropy or governments. Can anyone please come forward!

@chefjoseandres The audacity to think of demolishing a part of our White House for the personal preference of a ballroom. It is another example of governance for me, not of we the people.

that's probably not the roadmap you were hoping for. there's no secret lever to pull, no hidden strategy that makes this easier. the uncomfortable reality is that we're in a period where the old rules don't apply, and the new rules haven't been written yet. closed systems are getting stronger than open ones everywhere you look. power is consolidating in ever fewer hands. the trajectory is worrying, i admit.

but here’s the thing about history—it isn't deterministic. trajectories can shift. and they shift because people like you—people who refuse to stop showing up, even in the deep red parts of florida—keep the possibility of something better alive long enough for an opening to appear.

you're not alone. that's a fact. there are millions of people feeling exactly what you're feeling right now. the work is finding each other, supporting one another, and staying in the fight even when it feels hopeless.

thank you for what you're doing. thank you for not giving up. and thank you for writing.
