The 1994 Budapest Memorandum , states that “Taking into account the commitment of Ukraine to eliminate all nuclear weapons from its territory within a specified period of time” ..the following is agreed:
“Article 4. The United States of America, the Russian Federation, and the United Kingdom of Great Britain and Northern Ireland, reaffirm their commitment to seek immediate United Nations Security Council action to provide assistance to Ukraine, as a non-nuclear-weapon State Party to the Treaty on the Non-Proliferation of Nuclear Weapons, if Ukraine should become a victim of an act of aggression or an object of a threat of aggression in which nuclear weapons are used.”
The fact that Russia has broken its undertaking does not invalidate the agreement and imposes a responsibility on the remaining signatories to provide assistance to Ukraine. Why are they allowing themselves to be bullied and threatened by Putin? They have a legitimate ground for assisting; he has no legitimate ground for invading.
