Note that if Trump wants to shut the war down really fast, all he has to do is see to it that the US sends $200-billion to Russia. [Video included at the site.]
Vlad Putin: “We Are Ready to Speak with Trump – His Behavior When There Was an Attempt on His Life, I Was Impressed
[...]
Kremlin says reports that Trump and Putin spoke in recent days are 'pure fiction'
That is the problem when two compulsive liers meet uh?
https://www.youtube.com/watch?v=TyEOo1fqUCISeem the phone call did take place, but Putin is not interested in Trump's peace plan ideas.
“Donald Trump is realising how complicated this is going to be.”
Donald Trump’s reported call to Vladimir Putin backfires as the Russian leader “signals a willingness not to move on this issue”, says Julia Manchester, reporter in Washington DC for The Hill.
So what happens in the situation if Ukraine plays ball and sits at the negotiating table and Russia doesn't?
Well, if Putin was going to take Ukraine in three days and it seems that he has reached around 10% in three years, my guess is that Trump will reach peace in around...two years or so?
When you make a stupid promise like Trump either you are stupid or you are not and know you will not deliver. Alternative C is that he know something we do not. The way to end the war is conceed a lot but also threaten with providing real and decisive support to Ukraine. Trump is usually about carrot and stick, it is the way he has done shady family business all his life.
