Why NATO and the USA keep saying that Russia is a great threat to world security?

1. Military Aggression: NATO and the USA view Russia as a significant threat due to its military actions, particularly its annexation of Crimea from Ukraine in 2014. This move violated international law and raised concerns about Russia's willingness to use military force to redraw borders. Additionally, Russia's ongoing support for separatist movements in Eastern Ukraine and its military presence in Syria contribute to the perception of Russian military aggression.

2. Interference in Sovereign Affairs: Another reason for NATO and the USA's concern is Russia's interference in the internal affairs of other countries. This includes cyber attacks on Western institutions, meddling in elections, and spreading disinformation to undermine democracies. Such actions erode trust among nations and destabilize regions, posing a threat to the established international order.

3. Support for Authoritarian Regimes: Russia's support for authoritarian regimes around the world is also troubling for NATO and the USA. By aligning with regimes that suppress human rights and democratic principles, Russia undermines efforts to promote stability and democracy globally. This support allows autocratic leaders to maintain power and perpetuate conflicts, leading to increased regional tensions and security challenges.

4. Advanced Military Capabilities: Lastly, NATO and the USA are concerned about Russia's development of advanced military technologies and its modernization of its armed forces. From hypersonic missiles to sophisticated cyber warfare capabilities, Russia's military advancements pose a direct challenge to Western security interests. The combination of these factors contributes to the perception of Russia as a significant threat to world security, prompting NATO and the USA to closely monitor and respond to Russian actions.
