The only route for Putin to get to the talks in Budapest appears to be via Turkey, the Med and Serbia, since he can't overfly any other European countries.
FNN has another idea.
Putin is blasted on a Soyuz rocket from Kazakhstan into a low-earth orbit.
The landing module detaches to land him in the Danube exactly between Buda and Pest.
Putin emerges from the landing module in his spacesuit to shake hands with Trump who arrives on riverboat straight out of Apocalypse Now navigated by none other than Mr Clean himself - Larry Fishburne.
What a photo op!
