After the European leaders gave him some reality check, he's now willing to sign a treaty with US but his conditions still are continuation of war.
What Trump is suggesting is a ceasefire and peace deal which would allow US companies to enter Ukraine and with US companies directly involved in Ukraine, Russia would not dare to attack it. Zelenskyy and Trump are still in different reality. The mineral deal might be signed but it won't come into effect anytime soon.
There are lots behind the prolongation of the Russia and Ukraine ongoing war, but at this that the US cannot be able to intervene due to the laid down conditions which Zelenskyy see as not an alternative, then there might be some secrets sponsors backing the continuation of this war till they see that everything summoned under their own interest, I knew it, that a lot is going underground with politics and the war between the two countries.
