Biden's Hope for Ukraine's Counter-Offensive and NATO Membership

US President Joe Biden expresses hope that Ukraine's counter-offensive will bring Moscow to the negotiating table and believes Russia has already lost the war in Ukraine. Biden also pledges that Ukraine will eventually join NATO. However, NATO leaders did not provide a clear timeline for Ukraine's membership at a recent summit. Biden dismisses the possibility of Putin using nuclear weapons and warns Yevgeny Prigozhin, the chief of the Wagner mercenary group, to be careful of poisoning.
