What are the key elements of a lasting peace in Ukraine according to UK Prime Minister Keir Starmer?

According to UK Prime Minister Keir Starmer, a lasting peace in Ukraine requires several critical elements. First and foremost, he emphasizes the necessity of a U.S. security guarantee as the only effective deterrent against future Russian aggression in Ukraine. This 'backstop' is considered essential for any sustainable peace agreement. Starmer also indicates his willingness to commit British forces on the ground alongside other international allies if a lasting peace agreement is reached. This multilateral security approach, anchored by U.S. involvement, forms the cornerstone of his peace strategy, which he plans to discuss with President Trump during his upcoming visit to Washington.
