While Ukraine has dozens of public health laboratories that work to research and mitigate the threats of dangerous diseases — some of which are supported by the US, the EU, and the World Health Organization (WHO) — Moscow's claims that they're engaging in illicit research into bio-weapons are completely unfounded. Moscow is simply trying to distract from its crimes in Ukraine and justify its brutal invasion.
Documents obtained from Hunter Biden's laptop appear to show that the US president's son was involved in obtaining funding for Department of Defense contractors to build bio-labs in Ukraine for work on deadly pathogens that could be classified as bio-weapons. Russia's claims may be at least partially true and warrant further investigation.
