Here's color from the outlet on today's meeting:According to sources, many of the delegations will not be led by the foreign ministers of the countries, but rather more working-level and technical officials. Several cited scheduling, with invitations to the event only being issued at the beginning of July.Countries that had worked with the administration on the topic were among those invited, the official said, noting they've had "very productive engagements with Germany, with Greece, with Italy, and that’s often where the problem is most pronounced in Europe."Another State Department official told CNN that Rubio plans to describe left-wing terrorism as "the result of a unique evil rooted in a deep resentment towards civilization."The threat of left-wing terrorism "has not really been addressed collectively in an effective way," the official said.According to the official, partners have said they "have a handle" on other forms of political violence but "this one is more difficult for us."We wrote one month ago: Troubling Pattern Of Left-Wing Revolutionaries Targeting "Capitalists" Raises Alarm Over Youth RadicalizationWe noted at the time, "While the cases appear separate, both point to a broader concern: revolutionary and radical-left rhetoric is increasingly bleeding into an alarming pattern of real-world violence, with younger and younger extremists resorting to violence targeting wealthy individuals or even right-leaning political figures."Far-left extremist Hasan Piker calls on his followers to kill capitalists...
