Because he doesn't care to?
- He doesn't care about the Ukraine war except as a means to bully Zelensky for his pal Putin. He doesn't want the war to end because Putin doesn't either.
- He definitely doesn't care about ending the Gaza war, and in fact has encouraged Bibi to 'finish it'.
- I don't even know why specifically this time, but the US was never going to let another anti-American rebel group into power in the Middle East, cause that shit worked out real bad for the US gov't in Iran.
So, he's not ending wars because he doesn't want to? Wait, you're not are you surprised that the lying man known primarily for the absolute fire hose of lies that excretes from his face-hole lied, are you?
