美国总统特朗普美东时间3日凌晨证实，美军对委内瑞拉发动大规模军事打击，并抓走委内瑞拉总统马杜罗夫妇。 委内瑞拉中央大学石油工程学院教授拉米罗·罗耶罗：美国的目的既是地缘政治层面的控制，也是经济层面上对拉美地区原材料的掌控。 委内瑞拉石油产业专家指出，美国主要生产轻质原油，这类原油主要用于制造汽油，其他用途有限，而委内瑞拉拥有美国产量不足的"重质原油"，在美国市 场具有极强的互补性。 委内瑞拉中央大学石油工程学院教授拉米罗·罗耶罗：与轻质原油不同，重质原油提炼会产生凝析气，且衍生产品种类比轻质原油更丰富。重质原油可满足 全球对这类衍生产品的需求。 美国大部分炼油厂是按加工委内瑞拉石油的标准建设的，因此使用委内瑞拉原油而非本土原油，生产效率更高。 从最初号称打击所谓毒品犯罪，到封锁进出委内瑞拉的油轮，再到对委内瑞拉直接实施军事打击，美国一系列行动不断升级，矛头指向委内瑞拉石油产业。 美国自身是产油国，为何还长期觊觎委内瑞拉的石油？ 委内瑞拉目前已探明石油储量3000亿桶，约占全球已探明储量的17%，居世界首位。美国已探明石油储量810亿桶。不过，美国长期以来仍需进口石油，尤 其是委内瑞拉石油。 委内瑞拉"重质石油 ...

Core Viewpoint - Many in the Global South do not mourn the reduction of U.S. foreign aid, viewing it as an opportunity for self-development, as the U.S. aid system has historically been a tool for geopolitical control [1][2] Group 1: U.S. Foreign Aid System - President Trump initiated a "lightning strike" against the U.S. Agency for International Development (USAID), leading to its dismantling, which may result in the loss of the "humanitarian core" embedded in development [1] - The concept of "development" is often seen as contradictory by many in the Global South, as the aid system has been a means of maintaining global inequality and resource exploitation rather than alleviating it [1][2] Group 2: Reactions from the Global South - With the closure of USAID, the reality of the aid system's exploitative nature is becoming clearer, as organizations like the "Interaction" alliance express concern that attacks on USAID hinder projects supporting U.S. global leadership [1] - Some activists in the Global South are less worried about the reduction of aid, expressing a desire to end dependency on foreign assistance and focus on structural changes instead [2]
