Ukraine’s President Volodymyr Zelenskyy warned European leaders that any doubts they show before admitting Kyiv into the Nato alliance will embolden Russia to attack more countries, Report informs, citing foreign media.

“We must remember that every doubt we show here in Europe is a trench that Russia will definitely try to occupy,” he told a European summit in Moldova.

Ukraine is a candidate to join both Nato and the European Union, and Moldova the EU, but some European capitals are wary of setting a formal timeline for membership as Russia’s invasion continues.

But, addressing four dozen European leaders from inside and outside the union and the alliance, the Ukrainian leader warned that delaying a decision would undermine the West’s strength.

He complained that if Ukraine and Moldova have no clear path to joining the groupings, vulnerable pro-Western political forces in Belarus and Georgia will be at risk.

“Whether these doubts are about vital security steps or doubts about our unity, maybe about our ability to meet the challenges of our time, every doubt brings more insecurity,” he said.
