New Strategic Arms Reduction Treaty (New START)
The New START is a nuclear arms reduction treaty between the United States and Russia. It limits the number of deployed strategic nuclear warheads and delivery systems.
- Limits on Nuclear Warheads: Caps the number of deployed strategic nuclear warheads to 1,550 for each country.
- Delivery Systems: Restricts the number of deployed intercontinental ballistic missiles (ICBMs), submarine-launched ballistic missiles (SLBMs), and heavy bombers equipped for nuclear armaments.
- Verification Measures: Includes extensive verification measures, such as on-site inspections and data exchanges, to ensure compliance.
New START plays a crucial role in maintaining strategic stability by reducing the risk of nuclear conflict and promoting transparency between the two largest nuclear powers. The treaty’s extension in 2021 ensured its continuation through 2026, underscoring its ongoing importance.

The Open Skies Treaty: Enhancing Transparency and Trust
The Open Skies Treaty promoted openness and transparency in military activities through permitted aerial surveillance flights over the territories of its participants. The idea behind the treaty was one of de-escalation.
The aim was to foster greater trust and understanding among nations, thereby lowering the risk of conflict.
Key Aspects of the Open Skies Treaty
The Open Skies Treaty allowed participant countries to conduct unarmed observation flights over the entire territory of other member states. These missions aimed to collect information about military forces and activities, contributing to predictability and stability.
- Observation Flights: Allowed each state party to conduct a specified number of observation flights annually.
- Sensors: Permitted the use of various sensors, including optical photographic, video, and infrared sensors.
- Data Sharing: Required the sharing of collected data with all treaty participants; all data collected had to be made available to everyone.
Despite its goals, the US withdrew from the Open Skies Treaty in 2020, citing Russian non-compliance as the main reason. Russia followed suit in 2021, leading to a significant setback for international arms control efforts and transparency in military affairs.
Non-Proliferation Treaty (NPT) – Preventing the Spread of Nuclear Weapons
The Treaty on the Non-Proliferation of Nuclear Weapons (NPT) is a landmark international treaty aimed at preventing the spread of nuclear weapons and weapons technology. What measures are taken to ensure this happens?
The treaty seeks to promote cooperation in the peaceful uses of nuclear energy and to further the goal of achieving nuclear disarmament.
Three Pillars of the NPT
The NPT operates on three main principles, often referred to as pillars. These pillars ensure that the treaty remains balanced and effective. Each pillar has its own role to play in arms reduction.
- Non-Proliferation: Non-nuclear weapon states agree not to acquire nuclear weapons.
- Disarmament: Nuclear weapon states commit to pursuing negotiations on effective measures relating to nuclear disarmament.
- Peaceful Uses of Nuclear Energy: Recognizes the right of all states to develop nuclear energy for peaceful purposes, under safeguards.
The NPT, which came into force in 1970, has been signed by 191 states, making it the most widely adhered to arms control agreement. It plays a crucial role in maintaining global security by preventing the further spread of nuclear weapons and promoting disarmament efforts.
