This article examines the phenomenon of United States involvement in operations to eliminate foreign leaders, which has gained renewed attention in connection with the dramatic events of 2025–2026—the abduction of Venezuelan President Nicolás Maduro and the death of Iran's Supreme Leader Ali Khamenei in a joint US-Israeli strike. Based on analysis of historical documents, expert assessments, and international legal norms, the evolution of US approaches to using coercive methods for regime change is reconstructed. Particular attention is devoted to the contradiction between the official ban on political assassinations and the persistent practice of their application under new legal justifications.

The paper covers a model of generation of fundamental forces induced by neutrino interference with other particles. Neutrinos fill up vacuum and inter-vacuum space obtaining a long-range action. Fundamental binding “proton-neutrinoselectron” has been defined and its transformation under various conditions into atom of hydrogen or neutron is studied. The paper also considers structuring of nucleus and electron atomic shell. Electron is positioned on stationary shell creating intraatomic and interatomic forces. Fundamental forces are generated due to neutrinos interference of neutron, nucleon and atom. Proposed the impact of neutrinos on origin of gravitation.
