Ukraine’s president, Volodymyr Zelensky, argues that any US-organised peace agreement would have to be accompanied by “security guarantees” from the US to prevent Russia from resuming its offensive in the future.
However, Donald Trump has so far said the US will not commit to sending troops to Ukraine if Russia doesn’t stand by any such deal.
Another way of assuring a security guarantee would be for Ukraine to be allowed to join Nato. As a Nato member, Ukraine would be protected by Article 5 which states that if one member is attacked, others will come to its aid. But Trump has also ruled out this option.
