One positive from Trump's UN speech: Ukraine policy shift?

In surprise shift, Trump prods Ukraine, Nato to fight Russia and to take back the lands Russia now occupies by force and war? TACO Trump makes me wonder if he will not follow up this promouncement with anti-missile defense aid, severe sanctions against Russia, and other weapons and technology that Europe does not have. Will it inspire an effort both by the US and Europe to develop to keep up with the Russians? If this is a permanent change in Trump's policy and attitude toward NATO, only time is going to tell. I remain skeptical, but hopeful.
