"As the Polish experience reminds us, the defence of the West ultimately rests not only on means but also on the will of its people to prevail," Mr Trump said.
"The fundamental question of our time is whether the West has the will to survive."
He called on Russia to "cease its destabilising activities in Ukraine and elsewhere and its support for hostile regimes including Syria and Iran".
Instead, he said, Russia should "join the community of responsible nations in our fight against common enemies and in defence of civilisation itself".
