I haven't brought this up recently, but it should be noted that as the anniversary of Russia's invasion of Ukraine is coming up at the end of this month, we should remember the damage President Obama's legacy has taken.
We are thinking about supplying more lethal arms to Ukraine as Russia's aggression shows no sign of abating despite an oil price drop and sanctions.
But remember that Russia invaded Ukraine despite the guarantees that Russia, America, and Britain gave to Ukraine in order to get Ukraine to give up their nuclear weapons inherited from the Soviet Union when that empire collapsed.
Without nuclear weapons, Ukraine relied on the 1994 Budapest Memorandum as well as the UN charter to protect their territorial integrity.
Remember, too, that President Obama received the Nobel Peace Prize early in his first term as a sign of confidence in his potential to further nuclear disarmament.
If Russia gets away with ripping apart Ukraine, who will want to give up their nuclear weapons (or nuclear weapons ambitions) in exchange for American guarantees that they don't need them?
Of course, if the hope is that America will engage in unilateral nuclear disarmament, that hope is still alive, I suppose.
