Kiev: Ukrainian President Volodymyr Zelensky told a meeting of the UK-led Joint Operations Forces on Tuesday that NATO was the world's strongest alliance, but Russia has taken some of its members into its fold. The president warned European countries that if the Russian war was not stopped, it would target them too. "We can stop Russia," he said. We can save people from dying. We have to come together if we want to stop the destruction of democracy. If you don't do this, they will come after you too.' Criticizing the NATO alliance, the president said that his people currently rely on the support of international partners rather than the NATO alliance, the BBC reported. "Of course, Ukraine is not a member of NATO, we understand that," he said. We have heard about open doors for many years, but we have also heard that we cannot enter those doors.' He said other countries bordering Russia should consider their "independent defense capabilities" outside NATO.
