Guantanamo Bay was established in 2002 by President George W. Bush as part of the "war on terror" to detain terrorism suspects and "illegal enemy combatants" after the September 11 attacks[1][2].
However, Trump has recently signed executive orders to expand and repurpose parts of the Guantanamo Bay facility specifically for detaining "the worst criminal illegal aliens," including constructing new structures and preparing thousands of additional beds, marking a controversial expansion of its use[3][4][5][6].
In summary, while Trump did not establish Guantanamo Bay as a detention center, his administration has recently taken significant steps to expand its use and capacity for detaining migrants, raising renewed legal, ethical, and political debates about the facility’s future and purpose[3][5][6].
