As key reason for this, Russia cited recent US military actions including the US order of repositioning two nuclear submarines closer to Russian shores and deployment of Typhon missile system in Philippines. 

About INF Treaty

• Signed between the United States and the Soviet Union in 1987, the treaty required destruction of all ground-launched ballistic and cruise missiles with ranges of 500–5,500 km.
• It was the first major agreement to reduce nuclear arsenals, remove an entire class of weapons, and allow on-site inspections for verification.
• INF Treaty had already weakened after the US withdrew in 2019. 

Implications on nuclear arms control

• Breakdown of Arms Control Frameworks: Eroding trust and hindering efforts towards future nuclear disarmament movements.
• Negative impact on nuclear disarmament: Major powers accelerating nuclear modernization, while non-nuclear states are reconsidering their non-proliferation commitments, heightening global instability.
• Return to Cold War Politics: Collapse of treaty has stoked fears of a replay of Cold War-era European missile crisis. 
• Increasing Security Risk: Such weapons take less time to reach targets, raising the likelihood of a global nuclear conflict over a false launch warning.
