Judge, Jury, and Executioner: Drone Warfare and the Expansion of American Executive Authority (2001-2020)
This paper examines how the United States’ proliferation of unmanned combat aerial vehicles (UCAVs), or drones, have allowed the executive branch to concentrate its power to wage the post-9/11 War on Terror. This paper will examine the proliferation of drone warfare during the George W. Bush, Barack Obama, and Donald Trump presidential administrations and how they have expanded executive authority. Although historians have emphasized the moral and legal consequences of drone warfare such as its civilian casualties and potential violations of U.S. and international law, they have paid little attention to its impact on the distribution of power among the three branches of American government. Drones’ contribution to the expansion of executive authority is significant because they have allowed the president to unilaterally act as judge, jury, and executioner. Drawing on legal documents, Justice Department memos, transcripts of congressional hearings, statements made by politicians, the National Security Archive’s digital collection on Anwar al-Awlaki, newspaper articles, and scholarly accounts, this paper will argue that America’s transition to drone warfare has expanded the war powers of the executive branch. When we rethink America\u27s expansion of the targeted killings of suspected terrorists through the use of drones, it encourages us to think about how the War on Terror has given the executive branch the power to wage war almost unchecked. The executive branch as the sole arbiter of targeted killings has spawned problems in the American democratic system of checks and balances, and drones have been an influential tool in allowing this to occur
Serum Albumin Is Inversely Associated With Portal Vein Thrombosis in Cirrhosis
We analyzed whether serum albumin is independently associated with portal vein thrombosis (PVT) in liver cirrhosis (LC) and if a biologic plausibility exists. This study was divided into three parts. In part 1 (retrospective analysis), 753 consecutive patients with LC with ultrasound-detected PVT were retrospectively analyzed. In part 2, 112 patients with LC and 56 matched controls were entered in the cross-sectional study. In part 3, 5 patients with cirrhosis were entered in the in vivo study and 4 healthy subjects (HSs) were entered in the in vitro study to explore if albumin may affect platelet activation by modulating oxidative stress. In the 753 patients with LC, the prevalence of PVT was 16.7%; logistic analysis showed that only age (odds ratio [OR], 1.024; P = 0.012) and serum albumin (OR, -0.422; P = 0.0001) significantly predicted patients with PVT. Analyzing the 112 patients with LC and controls, soluble clusters of differentiation (CD)40-ligand (P = 0.0238), soluble Nox2-derived peptide (sNox2-dp; P < 0.0001), and urinary excretion of isoprostanes (P = 0.0078) were higher in patients with LC. In LC, albumin was correlated with sCD4OL (Spearman's rank correlation coefficient [r(s)], -0.33; P < 0.001), sNox2-dp (r(s), -0.57; P < 0.0001), and urinary excretion of isoprostanes (r(s), -0.48; P < 0.0001) levels. The in vivo study showed a progressive decrease in platelet aggregation, sNox2-dp, and urinary 8-iso prostaglandin F2 alpha-III formation 2 hours and 3 days after albumin infusion. Finally, platelet aggregation, sNox2-dp, and isoprostane formation significantly decreased in platelets from HSs incubated with scalar concentrations of albumin. Conclusion: Low serum albumin in LC is associated with PVT, suggesting that albumin could be a modulator of the hemostatic system through interference with mechanisms regulating platelet activation
