What to know:

• Friday’s milestone anniversary will bring memorial rituals to a day that about half of U.S. adults remember as one of the most historic events of their lifetime, according to a new Ipsos poll. President Donald Trump plans to attend a ceremony at the Pentagon. For the first time, this year’s New York commemoration will add a silent moment to honor people who were exposed to the clouds of toxic dust released by the twin towers’ fiery collapse and have since died of cancer and other illnesses. Questions remain about how many people developed health problems linked to the dust.

The US has made progress in reopening the Strait of Hormuz, but the Iran war is far from over

In recent weeks, the United States has succeeded in loosening Iran’s grip over the Strait of Hormuz while virtually shutting down Iran’s own oil exports, accelerating its economic free fall. But low-level fighting persists, the U.S. does not seem to have an exit strategy and the stalemate is costly for both sides. Read more.

Why this matters:

• The mounting economic pressure on Iran has yet to stoke an uprising, and if its leaders are backed into a corner, they may opt for military escalation rather than capitulation. Their Houthi allies in Yemen have meanwhile stepped up attacks on Saudi Arabia, helping to push oil prices back up. The price of a barrel of Brent crude surged above $100 this week, and diesel — heavily used in transport and farming — hit a record, potentially stoking inflation. President Donald Trump has acknowledged that gas prices are likely to stay high through the midterm congressional elections.

Vance? Rubio? DeSantis? Cruz? Republicans at Dallas convention ponder options for post-Trump leader

In interviews with nearly two dozen attendees, there was no clear consensus yet on a favored 2028 candidate. While potential front-runner Vice President JD Vance received plenty of mentions, a long list of others were on wish lists as well. And most said they weren’t ready to commit. Read more.

Why this matters:

• It reflects how completely the party has come to revolve around President Donald Trump in the decade since he seized control, making it difficult for some Republicans to consider a future without him at the helm. The uncertainty mirrors the wide-open field on the Democratic side, which is embroiled in its own soul searching.
