Kyiv has been calling on its partners to provide additional air defense assets as Russia intensifies its strikes against cities ahead of winter.Ukraine has received at least three Patriot systems from Germany and one from the U.S. Other countries, like the Netherlands and Spain, delivered individual launchers or missiles. The Netherlands delivered three new Patriot air defense launchers to Ukraine, Dutch Defense Minister Ruben Brekelmans announced on Nov. 28. “This saves lives and protects vital infrastructure. It is and remains in our common interest to stop Russian aggression,” Brekelmans said on social media. Will the systems really help in changing the course of the war ?
