One problem...none of those governments SUPPORTS such terrs, and they actively try to stop them. They've also had quite a bit of success since the heyday of those groups back in the '80s.
Where do the terrorists come from?
I gave you the answers.
The support for current-day terrorists comes from Saudi Arabia, Red China, Iran, and North Korea.
Agreed that none of them are "democracies."
OTOH, so what? There are about 100 nations which are not democracies AND which do not support terrorists.
