Larry Johnson runs the timeline:
So Lindsey Graham arrives in Kyiv by 11 am Friday morning. He meets with Zelensky and tours a drone factory. Then we are asked to believe that he returns to Washington, DC after spending less than 24 hours on the ground. Again, I call bullshit!!
The earliest train back to Warsaw departs Kyiv-Pasazhyrskyi at 07:40–08:00 on the 11th and arrives Przemyśl Główny in the afternoon (~17:00–18:00). That is at least nine hours. That would make it roughly 1100 hours in Washington, DC. Let’s assume he has an hour to get to the airport and the plane takes off at 1900 hours local from Poland. The flight going west takes 10 hours… This means the earliest the plane could have landed at Dulles is midnight on the 11th. That is 3 ½ hours after Graham reportedly died at home.
In other words, Sen. Graham probably died in a Russian missile strike. And the fact that the US government wants to hide that suggests that the USA is not actually willing to fight a direct war with Russia. And it may indicate why Trump rushed home from Europe babbling about assassination attempts.
If Russia has finally decided to start fighting back against its self-declared enemies, we may seeing the demise of some British and European leaders sooner rather than later.
