Estonia’s president, Alar Karis, has said it is prepared to contribute troops to an international reassurance force that the ‘Coalition of the Willing’ plans to send to Ukraine as a post-ceasefire security guarantee. He said  Estonia is not overly concerned that this would weaken NATO’s eastern flank, though discussions with alliance leaders continue. Lithuania and Latvia are also willing to participate, but Poland has declined, citing the need to protect its own borders. The reassurance force would be deployed only in non-contact areas within Ukraine. NATO secretary-general Mark Rutte noted that while NATO itself will not formally participate, the alliance is quietly discussing how to ensure resources are not overstretched. About 80,000 US troops are currently in Europe, but there could be a reduction in numbers as Washington’s foreign policy pivots towards the Indo-Pacific. The 'Coalition of the Willing' will meet again on 4 September; the security guarantees it will aim to provide for Ukraine following a truce are almost ready, but confirmation of US support is now needed.

Dutch prime minister Mark Rutte is set to become the next NATO secretary-general after Hungary lifted its veto, following a letter from Rutte to Viktor Orbán. The letter promised Orbán that, as NATO head, Rutte would not deploy Hungarian troops or use its funds to support Ukraine. The current secretary-general, Jens Stoltenberg, says the selection process will conclude ‘very soon’. Orbán posted the letter on social media, confirming Rutte’s commitment to the agreement. Rutte acknowledged past remarks which had caused dissatisfaction in Hungary and reassured Orbán of his respect for the deal made between Stoltenberg and Orbán in Budapest. His confirmation depends on consensus among all NATO members; with the veto lifted, he is now poised to succeed Stoltenberg.
