Protesters hold a Russian flag and signs reading "Hands off Venezuela" and "Stop USA Army" in front of the Presidental palace on February 12, 2019, in Bratislava, Slovakia, during a visit of the US State Secretary who is on a week-long tour across Central Europe. - The visits to Hungary, Slovakia and Poland intend to make up for a lack of US engagement that opened the door to more Chinese and Russian influence in the region.
