The President of the United States of America and the President of the Russian Federation, taking into account the threat posed by worldwide proliferation of missiles and missile technology and the necessity of counteracting this threat, agreed on the following basic principles to serve as a basis for further discussions in order to reach agreement in the field of demarcation between ABM systems and theater missile defense systems.
The United States and Russia are each committed to the ABM Treaty, a cornerstone of strategic stability.
Both sides must have the option to establish and to deploy effective theater missile defense systems. Such activity must not lead to violation or circumvention of the ABM Treaty.
Theater missile defense systems may be deployed by each side which (1) will not pose a realistic threat to the strategic nuclear force of the other side and (2) will not be tested to give such systems that capability.
Theater missile defense systems will not be deployed by the sides for use against each other.
The scale of deployment—in number and geographic scope—of theater missile defense systems by either side will be consistent with theater ballistic missile programs confronting that side.
In the spirit of partnership, the Presidents undertook to promote reciprocal openness in activities of the sides in theater missile defense systems and in the exchange of corresponding information.
