Betcha they wished they made a deal 2 years ago instead of listening to NATO.
You mean like the deal they made back in 1991 wherein Russia recognizes Ukraine's sovereignty of all of its territory in exchange for Ukraine handing over its nukes? How's that one working out for the Ukrainians?
Expecting honest dealing from Russia is like expecting an abusive man to beat his wife only on alternate Tuesdays.
If the US and other nations don't protect Ukraine now it will be impossible to convince any nation in the future not to arm themselves with nuclear weapons.
If Ukraine manages to fight off the Russians without our aid they will probably set about developing nuclear weapons.
And then we'll have another nuclear armed nation - one with some of the most modern drones and a large army with combat experience.
It is in the interest of our nation to have them on our side.
