What should European leaders do to participate effectively in Ukraine defense discussions?

European leaders should actively engage in the debate by presenting concrete proposals rather than simply complaining about being excluded from discussions. The speaker advises ramping up defense spending and ensuring continued weapons supplies and training support for Ukraine. Additionally, Europeans should develop specific ideas about security guarantees for Ukraine. This proactive approach would allow European nations to meaningfully contribute to the conversation rather than feeling sidelined, particularly as tensions rise and discussions about Ukraine's defense continue between major powers.
