NATO Secretary General Mark Rutte said Friday’s summit between President Donald Trump and Russian President Vladimir Putin in Alaska will be an important test for Putin.

Russia wants to include the topic of a reduction of NATO troops presence in any conversations about the future of Ukraine, Polish Prime Minister Donald Tusk told reporters on Wednesday.

Philip Breedlove, the former Supreme Allied Commander Europe for NATO, told CNN’s Wolf Blitzer he believes “anything durable and lasting” to end the conflict between Russia and Ukraine would need Ukraine’s approval in the process.

President Volodymyr Zelenskyy has stated that the post-war security guarantee for Ukraine must work like NATO Article 5, which provides for collective security and defence in the event of an attack on one of the member states.

The E3 letter follows months of diplomatic stalemate, particularly after a 12-day war between Iran and Israel in June.

Germany says it will work with Ukraine's Western allies to provide military aid worth up to $500 million. This aid will be delivered using a new NATO supply line.
