NATO is the most cost-effective option for preventing another war. It is the simplest and most logical solution. If Ukraine does not join NATO, we will have to create NATO within Ukraine, which means maintaining an army strong enough to repel aggression, financing it, producing and storing enough of our own weapons, and negotiating with our partners about their participation to deter Russia from starting another war. That’s why we are talking about a comprehensive system of security guarantees—military, economic, and political. We need to weigh everything—what is cheaper, what is more realistic, and what can be done faster. I am grateful to everyone who supports Ukraine in our work toward real security.
