A simple search got me the list, but now the problem is to import them into Wunderlist. Being on MacOS, it took me sometime to understand how apple-script + automator work, but at the end, it was trivial.
1. Goto Automator - New - Workflow
2. Add an AppleScript and paste the following
set U to {"Algeria", ... "Zimbabwe"}
repeat with i from 1 to number of items in U
set X to (item i of U) as text
tell application "Wunderlist"
activate
tell application "System Events"
delay 0.25
keystroke "N" using command down
delay 0.25
keystroke (X)
keystroke return
end tell
end tell
end repeat
The above script in Automator types out the list into the Wunderlist application. Quick and dirty but does the job.
