This week, Les, Rob, Carmen, and Jamil discuss the massive underwater volcano eruption near Tonga and Russia’s dismantling of the hacker group known as REvil. They will also cast their predictions on whether or not Russia will invade Ukraine. Is the eruption of Hunga Tonga-Hunga-Ha’apai a national security issue that Americans should care about? What does it mean for Russia to dismantle REvil?
