Rather ironic don't you think since Ukraine gave up a nuclear arsenal as a quid pro quo for security guarantees contained in the Budapest Memorandum of 1994 and it was Russia which suspended the new START treaty.
Ukraine never had nukes. The Soviet Union had nukes and Russia was the successor state to the Soviet Union. Ukraine were not signatories to the NPT (non proliferation treaty) and between 1991 and 1994 were effectively a nuclear power outside the NPT. The Budapest Memorandum (much misrepresented in western msm whose distortions are then repeated by indoctrinated drones) was not "Ukraine giving up it's nukes", as per western msm. You always completely ignore the context of the agreements and memorandums that you invoke. You also repeat verbatim the same distortions and misrepresentations that you have been fed.
The nukes could not be used by the Ukrainians because they couldn't break the Russian codes. They agreed to sign the NPT and transferred the nukes to be destroyed. The world wouldn't exist today if Ukraine had usable nukes and you should be careful what you wish for in your blind hatred of anything Russia. Ukraine, being the corrupt country that it is, set a price for giving back the nukes. This has since been spun to death in western media and the same one one line repeatedly quoted, "respect the independence...", as if that is the entire Budapest Memorandum.
Your mentioning of the START treaty demonstrates that you simply repeat MSM headlines. You are like a talking Action Man doll who has about 10 phrases when you pull the string on it's back.
The US pulled out of treaty after treaty and sabotaged START to such an extent (wanting access to Russian nuclear silos whilst denying quid pro quo access) that the failure of START, as with every other nuclear arms threat reduction treaty, is entirely at the feet of the US.
Do you believe that Ukraine should have been able to retain nuclear weapons despite being a non signatory of the NPT at the time? Should Russia have given it the codes? What do you think should have happened given the circumstances? A newly independent state that by accident of geography is left holding nuclear weapons.
Imagine, for instance, if Scotland had voted to leave the UK in 2014. Should Scotland keep it's nuclear missiles based there as part of the UK? Should Scotland become a nuclear armed state in these circumstances? Would Scotland be "giving up it's nukes" by agreeing to transfer for destruction the nukes that it couldn't use? Unless the successor state to the UK-did it ever have nukes to give up?
Ukraine, "gave up it's nukes" because it couldn't use them. Had Ukraine been able to use the nukes, it would have used them and definitely not agreed to their transfer and destruction. It still extracted a price for this because it is corrupt.
Would you trust those in control in Ukraine to act responsibly with nuclear weapons?
