In an exclusive interview with the BBC, Merz stated: "We must do more on our own and we have been free-riders in the past," addressing US criticism over Europe's defense funding. He believes that a robust partnership with the UK is crucial to countering threats from Russia. The newly signed treaty not only renews mutual defense commitments but also prepares the groundwork for collaboration in technology and military exports. Plans for a direct rail route from London to Berlin were also discussed to enhance youth exchanges.

Merz is keen to foster stronger European unity and independence in security matters, reiterating the importance of young voices in shaping future relationships across the channel.
