Yanis Varoufakis is a performance actor who desperately tries to stay relevant by clumsily inserting himself into whatever is going on in the world. That's all there is to him. He's chasing the public spotlight like a dodgy personal injury lawyer is chasing ambulances.
I'm also starting to get really tired of this baseless genocide slander that is being repeated as if it was a religious mantra. The whole idea behind accusing Israel of it is twofold: It's meant to hurt Jews (who were victims of an actual genocide) and it's meant to distract from the genocidal ambitions of Israel's enemies.
