美国从巅峰滑落，始作俑者浮出水面，不是拜登，不是特朗普

Group 1 - The article argues that the real factors leading to America's current predicament are rooted in the policies of former President Obama, rather than solely blaming Trump or Biden [1] - Obama inherited a challenging situation in 2009, with the U.S. deeply involved in Iraq and Afghanistan, leading to significant debt accumulation, but also had opportunities due to international political capital gained from the War on Terror [3][5] - The international context was relatively favorable for Obama, with the U.S. maintaining strong military deterrence in the Middle East and a cooperative relationship with China, which helped stabilize the global economy post-2008 financial crisis [7] Group 2 - Despite having a favorable starting position, Obama chose to pursue aggressive foreign policies, such as pivoting to Asia and igniting the Arab Spring, which destabilized the Middle East and led to the rise of ISIS [9][11] - The push for domestic manufacturing was undermined by confrontational policies towards China and chaotic interventions in the Middle East, creating a disconnect between domestic economic needs and foreign policy actions [11] - Obama's administration saw a significant decline in traditional industries, with coal employment dropping from 830,000 to 500,000 between 2009 and 2016, contributing to the rise of populist movements like Trump's MAGA [11][13] Group 3 - The renewable energy sector, while appearing vibrant, failed to achieve expected growth, with subsidies primarily benefiting large corporations rather than fostering competitive industry clusters [13] - Policies emphasizing ESG (Environmental, Social, and Governance) and DEI (Diversity, Equity, and Inclusion) led to increased corporate costs and inefficiencies, shifting focus from productivity to political correctness [13] - The social fabric of the U.S. was fragmented under Obama's leadership, with identity politics leading to divisions and conflicts, ultimately weakening national cohesion [13]
