Perhaps Arafat would have fallen into the dustbin of history if he hadn't gained the support of the Soviet KGB. Arafat's success in organizing and motivating terrorists caught the KGB's attention, which during the '60s was developing "liberation fronts" throughout third-world countries. With the KGB's help, Arafat became the leader of the PLO. He intensified his terrorist activity and became a pioneer in hijackings, kidnappings, and other modes of terrorizing civilians.One can only wonder if the Soviets did this because they thought Islamofascism, unlike nazism, was incapable of betraying them the way the nazis did when they felt the scales had tipped in their favor. They'd be wrong, and with Islam's presence in the areas around Russia today, it's clear why they're just as vulnerable as any other European country.
So why would world leaders like Nelson Mandela become mouthpieces for someone like Arafat? Because Arafat rebranded himself and his cause to destroy Israel into a humanitarian crisis. And the world fell for his trick.
The KGB knew that Arafat would never get the additional support he needed to destroy Israel if he kept saying that he wanted to destroy Israel. So they sent him to the "reform school" of the Romanian dictator Nicolai Ceauşescu, a master of propaganda.
This also tells why I'm glad Ceausescu was finally defeated in the late 80s. Yet the damage even people like him did by bolstering the PLO has been done. Thankfully, he's now since gone to face the highest court along with Arafat.
