Hamas, the PLO, and so on do not represent any legitimate government.

N. Korea Kim Jong very ****ing Ill is a terrorist who heads up a
government.

He is a terrorist?


He sells weapons to terrorists.

In the 80s the USA were training and supplying weapons to Bin Laden &
Cie in order he fight against the Afghan communist government and their
allies, the Soviets.
At this time the Soviets were saying "Bin Laden is a terrorist" and USA
were saying "Bin Laden is an ally".
Do you think that at this time USA were a terrotist nation since it was
supporting a "terrorist" ?

At this time Bin Laden wasn't representing any government.
Would you say that he was an illegitimate ally of USA ? :-)
