Vice President Vance claimed in a brief Greenland visit on Friday that Denmark had failed to keep Greenland safe, and that President Trump is prepared to make the Arctic island "much more secure" and stronger economically.

Why it matters: Trump reiterated his argument before Vance's trip that "we need Greenland," with the added warning that "we'll go as far as we have to go" to get it. But the future Vance seemed to propose was not of U.S. ownership but of an independent Greenland opting into a new security and economic partnership with the U.S.

BlackRock will not sign an agreement next week to buy two Panama ports from Hong Kong's CK Hutchison, as originally planned, a source tells Axios.

Why it matters: President Trump touted this deal in his recent address to Congress, and it seemed like an offramp for U.S. threats to retake control of the Panama Canal.

Despite lots of recent chatter, there are strong reasons not to expect a rebound of Russian pipelined gas to Europe, a new analysis argues.

The U.S. gave Hamas a new proposal through Qatari mediators in an effort to release American hostage Edan Alexander and break the stalemate in the Gaza ceasefire negotiations, one U.S. official and one Israeli official said.

Why it matters: About $303 billion of imported drug, biotech and device industry goods entered the United States in the last year — $294 billion of which entered duty-free, according to PwC.

It's not just the Situation Room or Signal — senior Trump administration officials bypassed a range of secure government systems when they decided to discuss plans for an upcoming attack in Yemen on a commercially available app.

• Axios spoke to one current senior U.S. official and five former senior U.S. officials — all of whom have taken part in communications around similarly sensitive overseas operations — about the secure channels through which these conversations are supposed to happen, why turning to Signal could seem appealingly expedient, and why doing so is potentially dangerous.
