On Friday, Kellogg, a retired general with 56 years of military service, visited a military hospital in Irpin, where he met with veterans who have undergone limb amputations.
"The main reason I'm here is that President Trump wants to stop the killings," he stated.
He met with about 20 Ukrainian soldiers, speaking with each of them individually, according to a report by Sky News. One of the Ukrainians asked him, "Can we trust Russia and negotiations with them?"
"Great question," the general replied. "You need to look into history. You must be able to negotiate. All wars end in negotiations; even a final victory on the battlefield concludes with diplomacy."
"Sometimes it's hard for a soldier to agree with diplomacy, but what a soldier does is give politicians and diplomats time to come to an agreement. That’s why I say that Ukraine owes you, and the world owes you, because you are essentially sacrificing yourselves to allow diplomats to find... a good way out, the exit you have fought for."
Kellogg mentioned that a good question for him would be: "Can we trust the people we are with and be sure that we are together? It’s as if you’re asking the question — are you with us? And the answer is yes, we are with you," he said, referring to the United States.
The 80-year-old Kellogg is a veteran of the Vietnam War, the U.S. invasion of Panama, and the Iraq War.
