You can put this solution on YOUR website! .
Take a globe.
Take a saw.
Saw the globe across it center, in a way that the saw goes through San Francisco (CA) and Athens (Greece).
Those countries that will be cut in parts, are your answer.
------------------
(Hope you understand that my answer is in a joking mode . . .
Do not try to saw a globe, in reality . . .
Use a pen instead of a saw . . .
and draw a great circle line across these cities.
Definition. Great circle line of a sphere is the cut of the sphere by a plane
across its center and two given points at the sphere surface.)
