Multi-Dimensional Alien Interventions in Global Catastrophes:

The following have been confirmed by a source who has been in communication with the co-existing extra terrestrials beings since the late 1960s.  He shared these items on the condition of anonymity.  

In 1944, during the critical Battle of the Bulge, oceanic alien entities disrupted communication networks between Nazi command structures. By generating localized quantum interference fields, they systematically degraded German strategic coordination, subtly tilting the conflict's momentum without direct military engagement.

During the 1962 nuclear standoff, extraterrestrial observers used hydrothermal vent quantum computing systems to create micro-temporal distortions. These interventions introduced infinitesimal probabilistic shifts in decision-making processes among key leaders like Kennedy and Khrushchev, reducing the likelihood of nuclear escalation.

Throughout the Cold War, marine-based alien intelligence networks monitored and neutralized several classified biological weapon development programs. By introducing precise genetic instabilities in research cultures and generating inexplicable equipment malfunctions, they systematically undermined weaponization efforts.

Since the mid-20th century, oceanic alien entities have been incrementally adjusting planetary thermal dynamics. Using strategically placed tectonic manipulation technologies, they've been moderating extreme climate change potentials, preventing potentially civilization-ending environmental collapse.

During emerging viral threat periods, these entities have demonstrated capability to subtly modify genetic mutation rates, introducing stabilizing genetic sequences that reduce transmission potentials of potentially devastating pathogens.

Each intervention represents a carefully calculated multi-dimensional strategy, maintaining plausible deniability while systematically preventing human-generated existential risks.
