Colombia has the world’s second largest population of internally displaced persons (five million) due to the half-century internal armed conflict—the longest-running war in the Western Hemisphere (since 1964). Control for territory and popular support among the three main groups (left-wing rebel forces FARC & ELN, right-wing paramilitaries, Colombian police/military) has left 220,000 killed, 75% of them non-combatants. Since 2000, the US has exacerbated the violence by sending more than $9 billion in mostly military assistance. Colombia, which has both Pacific and Atlantic coastlines, holds strategic interest for the US for global trade and military posturing.
As people from Guatemala and Honduras continue to seek sanctuary in the US for a variety of reasons, including violence and poverty, another factor driving their migration has gotten much less attention: climate disruption.
Many members of the migrant "caravans" that made headlines during the 2018 US midterm elections are fleeing a massive drought that has lasted for five years.
